[Keyboard] Refactor HB85 to get rid of custom i2c code (#5570)
* remove dependency on custom i2c code * missed a pragma once * fix readme install instructions * config.h cleanup * make the bootmagic key not the same bmc reset key * disable bootmagic functionality as it doesn't seem to work on atmega32a bmc boards
