Subject: Helix-serial.c configuration improvement (#4370)

The new simple API can be selected.

Previous version, can select two way.
  * use old API (compatible with let's split serial.c)
  * use new API (multi-type transaction)

This version, can select three way.
  * use old API (compatible with let's split serial.c)
  * use new API (single-type transaction)
  * use new API (multi-type transaction)

There is no change in the code generated by this change.
