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.
