[Keyboard] Refactor HB85 to get rid of custom i2c code (#5570)

Browse Source 
* 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

ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods.
**Reset Key:** To put the HB85 into reset, hold F3 (`K00`) while plugging in.
**Reset Key:** Hold down the key located at `K00`, commonly programmed as F3 while plugging in the keyboard.
Windows:

brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
4. Place your keyboard into reset.
5. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file.
**Please Note:** You will need to use the `EEP_RST` keycode first, followed by unplugging/replugging the board to get RGB underglow effects to work.
