Subject: Add Suspend functions (#3112)

* Add suspend functions

* Disable RGB code if it's disabled

* Add suspend code to ChibiOS for future compatibility

* Add keyboard_init functions

* Change where references so it will compile

* Wrong command chained in wake up kb function

* Fix non-feature file changes

* Add documentation

* Re-add matrix init docs

* add rgblight code to example

* Remove keyboard init stuff for separate PR
