* Remove custom backlight code for PS2AVRGB boards
* Remove custom driver setting
* BACKLIGHT_BREATHING goes in config.h, not here
* Don't need to include backlight.c again here either
* Turn on backlight for Canoe
* Disable console on a few boards due to oversize
* Update keyboard kit URL
* Replace custom RGB driver with new one from #7183
* Replace backlight with standard impl
* Remove some unnecessary default settings
* Disable COMMAND since docs want it off by default
(There's no working IS_COMMAND set for this board anyway, so it's
already a nop.)
