Use White channel on RGBW LEDs (#7678)
* Use White channel on RGBW LEDs
Co-authored-by: kwerdenker <sebastian.spindler@gmail.com>
* Manually apply white channel to array
* Move where convert_rgb_to_rgbw is called
* Fix type for rgbw led struct
* Add changes to Ergodox EZ
can revert if deemed necessary
* Revert "Add changes to Ergodox EZ"
This reverts commit aa44db198d40d758ca10470eb94615513592d1dd.
* Revert "Fix type for rgbw led struct"
This reverts commit c5c744cba040201cc0d124400773cf13f8a2cf22.
* Revert "Move where convert_rgb_to_rgbw is called"
This reverts commit cd7f17caf6dd30731c54b3be54490fe4519444f9.
* Revert changes and fix up functions
* Enable white channel for Ergodox EZ as well
* Only run conversion of rgblight is enabled
