Version History:
v2: - Remove the Add output bus format negotiation patch from the series, as we use ouput format as MEDIA_BUS_FMT_FIXED and that is the default value if atomic_get_output_bus_fmts function is not implemented. - Return NULL if output format is not MEDIA_BUS_FMT_FIXED. - Return the supported color formats based on the display info structure.
