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.
