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

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* 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
