Add support for Atmega32A to pin declarations and universal matrix (#4015)
* add computed pins from mcu type
* update for atmega32a
* doc typo
* add atmega16 chips, link to references
* remove avr include from config
* exclude assembler in config.h includes
* consolodate options, add 646
* fix typo in pindef
