Two input event codes are added for keyboard LED mode switching prev/next. The keyboard has many of the same key outputs as the existing G752 keyboard including a few extras, and varies a little between laptop models. Additionally the keyboard requires the LED interface to be intitialised before such things as keyboard backlight control work. Misc changes in scope: update some hardcoded comparisons to use an available define, change "Mic Toggle" to use a keycode that works.
