Initialize and use the color_fill properties for planes in DPU driver. In
addition, relax framebuffer requirements within atomic commit path and
add checks for NULL framebuffers. Finally, drop DPU_PLANE_COLOR_FILL_FLAG
as it's unused.
Changes since V2:
- Fixed dropped 'const' warning
- Dropped use of solid_fill_format
- Switched to using drm_plane_solid_fill_enabled helper method
- Added helper to convert color fill to BGR888 (Rob)
- Added support for solid fill on planes of varying sizes
- Removed DPU_PLANE_COLOR_FILL_FLAG
