Tested on MT8195 and confirmed both correct video output and improved DRAM
bandwidth performance.
v4:
* Move modifier validation to format_mod_supported function.
* Add modifiers to drm_universal_plane_init() call.
* Make comparisons to DRM_FORMAT_MOD_LINEAR explicit rather than relying on
DRM_FORMAT_LINEAR being equal to 0.
* Gate AFBC control bit writes on device compatibility.
v3:
* Replaced pitch bitshift math with union based approach.
* Refactored overlay register writes to shared code between non-AFBC and
AFBC.
* Minor code cleanups.
v2:
* Marked mtk_ovl_set_afbc as static.
* Reflowed some lines to fit column limit.
