drm/format-helper: Add drm_fb_build_fourcc_list() helper
Add drm_fb_build_fourcc_list() function that builds a list of supported
formats from native and emulated ones. Helpful for all drivers that do
format conversion as part of their plane updates. Update current caller.
v3:
* improve warnings on ignored formats (Sam)
v2:
* use u32 instead of uint32_t (Sam)
* print a warning if output array is too small (Sam)
* comment fixes (Sam)
