[Bug] Using RGBLIGHT breaks split keyboards #24725

Describe the Bug

Currently all of our (splitkb.com) keymaps/keyboards which uses RGBLIGHT are broken. Full list shown below. Broken here is defined as: Unresponsive, garbled OLED and stuck RGB. So basically the whole keyboard is locked up. Interestingly when plugging the left side of the keyboard in to the host. The left side itself does seem to work correctly but not the right side. But when the right side is plugged in, both halves do nothing.

Going back through the PR/commit history I've found that the following PR/commit broke the keyboard behavior: #24364

Broken keymaps/keyboard which have been tested (and all use RGBLIGHT):
splitkb/kyria/rev3:default
splitkb/kyria/rev3:debug
splitkb/aurora/helix/rev1:debug
splitkb/aurora/corne/rev1:debug
splitkb/aurora/lily58/rev1:debug
splitkb/aurora/sofle_v2/rev1:debug
splitkb/aurora/sweep/rev1:debug

These were all compiled with the -e CONVERT_TO=liatris option.

I can imagine more keyboards are broken which are split and still uses RGBLIGHT.

Additional Context

Solution could be that we change all our broken keymaps to use RGB_MATRIX. But it's probably better to fix the bug within RGBLIGHT as more boards could be affected.
