WS2812 Overhaul (#210)
* ARM - ws2812 bitbang (#7173)
* Initial ARM bitbang ws2812 driver
* Unify chibios platform to run rgblight_task
* Remove 'avr only' comments from ws2812 docs
* Remove 'avr only' comments from ws2812 docs
* Unify chibios platform to run rgblight_task - review comments
* Remove debug flags from keymap
* Add comments from review
* Add defines for STM32L0XX
* Attempt to get arm ws2812 working on multiple gcc versions
* Support RGBLIGHT_SLEEP when ChibiOS boards suspend (#7280)
Copypasta from the AVR suspend implementation with a Teensy-specific
hack removed
* Unify RGB and RGBW commands (#7297)
* Fix unicode in comments

* Remove separate RGBW implementation for a unified function
* Set White to 0 in RGBW LEDs
This is just to get this working, later, proper brightness can be handled elsewhere.
* Use us instead of nanoseconds(?) since it renders correctly on web
* Remove RGBW function from arm/ws2812.h
* Remove RGBW function from arm/ws2812.c
* Formatting changes
* Add doc info
* Remove force of debug on within rgblight - causes lockups waiting for hid_listen (#7330)
* Move Ergodox EZ RGB Light code to custom driver (#7309)
* Move Ergodox EZ RGB code to custom driver
Also implements full addressing of Ergodox EZ's LED Strip, as written by seebs

* Make Clipping range accessible for custom drivers
* Remove RGBW_BB_TWI from driver and docs
* Revert changes to clipping range support
* Use just rgblight_set instead of full custom driver
* Convert to i2c_master commands
* Rename rgblight driver and clean up includes
* Use White channel on RGBW LEDs
* SPI DMA based RGB Underglow for STM32 (#7674)
* Initial stash of ws2812 spi driver
* Update comment, add sync backup plan
* Add testing notes to spi ws2812 driver
* Align RGBW error messages
