drm/ingenic: Implement proper .atomic_get_input_bus_fmts

Browse source

The .atomic_get_input_bus_fmts() callback of our top bridge should
return the possible input formats for a given output format. If the
requested output format is not supported, then NULL should be returned,
otherwise the bus format negociation will end with a bus format that the
encoder does not support.
