SURFACE_PIXEL_FORMAT_GRPH_ABGR8888 already listed in
amd/display/dc/dc_hw_types.h
and the necessary crossbars register controls to swap red and blue channels
are already implemented in drm/amd/display/dc/dce/dce_mem_input.c
Logic to handle new formats is added in amdgpu_dm and dce 8.0, 10.0, 11.0
modules.
