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
