[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
