Final HS60v2 changes. (#4790)

* initial commit, this now mostly works

- RGB controls work
- Dynamic keymap still broken due to eeprom
- Via works

* STM32 eeprom update

- Update EEPROM emulation library to handle 8bit data like AVR.
- This library also allows for multiple page pairs resulting in greater EEPROM size flexibility

* hs60 changes

* HS60 hhkb added

* Update keyboards/hs60/v2/config.h
