[Keyboard] LFK78 refactor (#7835)

* Change include guards to pragma once

* Clean up default keymaps

* Remove some magic numbers and use GPIO macros

* Clean up keyboard.[ch]

* Tidy up info.json and readme

* Align config.h with template

* Split up revision code into subfolders

* rev C-H has no audio, apparently

* Change revc_h to revc and document differences

* Turn off Audio on revb for now, for Travis' sake

* Split info.json into revision folders

* Clean up default keymaps some more
