Zeal60/Zeal65/M60-A implementation (#3879)

* Initial version of zeal60

* WIP

* Fixes issue #900

* Adding RGB underglow functionality.
Fixed a compile-time conflict caused by enabling RGB underglow functionality.

* Refactor RPC protocol

* Fix last merge

* README for RGB underglow updated.

* Additional README changes.

* Adding RGBW strip software-based current-limiting functionality.

* RGBW current-limiting functionality should be handled by RGBSTRIP_MAX_CURRENT_PER_LIGHT instead.

* Updated README to reflect implementation of built-in current limiting.

* Keymap readability improvements.

* Minor keymap improvements.

* Fixed LED driver init sequence, formatting

* Dimming implementation tested, working.

* Stab LEDs synced with spacebar hits in effects.

* RGB underglow tested and functional. Simplified README for RGB underglow.

* Undid accidental file deletion from previous merge conflict. Safer values for RGB underglow.

* Improved arrow key positions in keymap.

* Added functionality to correct uneven RGB underglow. Refactored related code.

* Reverted to safer values for underglow.

* Changes for v0.3

* Custom LED brightness scaling will take place after current adjustment in order to avoid being overridden.

* Create keymap.c

Added split backspace and split shift to ISO layout

* Create config.h

Turned on LEDs for new layout

* Fixed bug where left spacebar stabilizer LED (LC06) would adopt color of row above.

* Added hhkb_wilba keymap

* Update keymap.c

* Update keymap.c

* Update keymap.c

* Added indicators, full param setting via host

* Added "mousekey" layout

* Added Zeal65 support, factory test mode

* Keycode safe range changed, caused bugs

* Bumped EEPROM version due to change in QMK keycodes

* Disable HHKB "blocked" LEDs if KC_NO in keymap

* Added "disable_hhkb_blocker_leds"

* Required overridden function for keymaps in EEPROM

* Added polar coordinate mapping, effect speed

* Force Raw HID interface number to 1 always

* Fixed last merge from master

* Added effect speed to default keymaps

* add BACKLIGHT_ prefix to vars

* add BACKLIGHT_ prefix to vars

* Keymap speed effect; keymap improvements/fixes
Readme updated to match changes

* Refactored to use common IS31FL3731/I2C drivers

* Fixed make rules, backlight disabled feature

* Make split rightshift default for Zeal65

* Added M60-A as a "version" of Zeal60.

* Renamed IS31FL3731 driver functions

* Fix suspend_wakeup_init_kb() being defined twice

* First pass refactor dynamic keymaps

* Updated to changed I2C and ISSI drivers

* Refactor zeal_color.* usage to quantum/color.*

* Updated Zeal65, fixed dynamic_keymap

* Major refactoring of Zeal60 backlight and API

* Lots of little cleanups

* Added readme.md

* Added readme.md

* Added LAYOUT_60*() macros, refactored and cleaned up default keymaps

* Fix compile error in suspend.c

* Added Zeal65 LAYOUT macros, info.json

* Added rama/m60_a, deleted zeal60/keymaps/m60_a

* Fixed rama/m60_a/keymaps/proto

* Fixed compilation error for suspend.c

* Requested changes for PR

* Fixed readme.md images

* Another readme.md fix

* Added drashna's requested changes

+# RGB Underglow Strip on the Zeal60: A Guide
+
+<img src="https://i.imgur.com/UuUdOCb.jpg" width="800">
+
+## Requirements
+
+- WS2812B RGB strip, preferably 60 LEDs/meter
+- Wire, solder
+- Tape, hot glue, or some sort of adhesive
+
+## A. Connecting the strip
+You might find the [**full PCB image**](https://cdn.shopify.com/s/files/1/0490/7329/files/zeal60jumpers.png) helpful. Ignore the red boxes!
+
+1. Connect V+ to the receiving end of the thermistor labeled F1; connect GND to the board's GND pin. (*Avoid connecting +V to the board's +5V pin* - you will likely overload the thermistor, and you will limit your maximum brightness.)
+
+    <img src="https://i.imgur.com/jd7qivh.png" width="300">
+
+2. Connect DI to PB0.
+
+    <img src="https://i.imgur.com/BiMyMLv.jpg" width="300">
+
+3. Should look something like this when finished:
+
+    <img src="https://i.imgur.com/ngxYMuA.jpg" width="600">
+
+*Optional:* To allow considerably more light to escape, consider angling the strip outwards by using some sort of fulcrum under the strip. (I used a thick wire.)
+
+## B. Enabling the strip
+1. If it is not present already, add the following to your ***keymap's*** ```Makefile```:
+
+    ```Makefile
+    RGBLIGHT_ENABLE = yes
+    AUDIO_ENABLE = no     #Underglow animations cannot be used with audio.
+    ```
+2. If it is not present already, add the following to your *keymap's* ```config.h```, and edit the values as necessary:
+
+    ```c
+    // Set up RGB underglow.
+    #define RGB_DI_PIN B0          // The pin your RGB strip is wired to
+    #define RGBLIGHT_ANIMATIONS    // Require for fancier stuff (not compatible with audio)
+    #define RGBLED_NUM 35          // Number of LEDs
+    #define RGBLIGHT_HUE_STEP 5    // How much each press of rgb_hue changes hue
+    #define RGBLIGHT_SAT_STEP 10   // How much each press of rgb_sat changes sat
+    #define RGBLIGHT_VAL_STEP 10   // How much each press of rgb_val changes val
+    ```
+3. If they are not present already, add the following keycodes to your keymap to control the RGB strip: ```RGB_TOG``` (on/off), ```RGB_MOD``` (step through modes), ```RGB_HUI```, ```RGB_HUD```, ```RGB_SAI```, ```RGB_SAD```, ```RGB_VAI```, ```RGB_VAD``` (HSV increase/decrease). Add these to your keymap.
+
+## C. Dealing with current limits
+USB 2.0 ports on laptops provide up to 500mA max, but USB 3.0 ports can provide up to 900mA; USB 3.1 up to 1.5A; and powered USB hubs even more. We can run our keyboard at a higher brightness if we draw more power. **The Zeal60 uses 500mA at max brightness.** This means that **you have about 400mA remaining for the strip to use on a USB 3.0 port**; 1000mA free on a USB 3.1 port, so on and so forth.
+
+***Warning:*** **This means you will need to turn *off* your RGB strip before connecting to a USB 2.0 port**, as USB 2.0 cannot sustain the current necessary!
+
+1. If not present already, add the following to your keymap's ```config.h```. Change the numbers based on your needs. The ones below are safe underestimates.
+
+    ```c
+    // Enable current limiting for RGB underglow.
+    #define RGBSTRIP_CURRENT_LIMIT 400    // Strip current limit in mA. (USB amperage - 500mA for keyboard)
+    #define RGBSTRIP_MAX_CURRENT_PER_LIGHT 50 // mA per light when at max brightness.
+    ```
+    *Example:* I use a USB port capable of providing 1800 mA. The keyboard uses 500mA, so my personal value (in the `tusing` keymap) for `RGBSTRIP_CURRENT_LIMIT` is 1300. The particular WS2812B RGB strip I have uses a maximum of 60 mA per LED, so that is my personal value for `RGBSTRIP_MAX_CURRENT_PER_LIGHT`.
+2. Toggle on the LED strip (```RGB_TOG```) and step through animations (```RGB_MOD```) to test it out!
