drm/display: bridge_connector: handle ycbcr_420_allowed
Follow the interlace_allowed example and calculate drm_connector's
ycbcr_420_allowed flag as AND of all drm_bridge's ycbcr_420_allowed
flags in a chain. This is one of the gaps between several
bridge-specific connector implementations and drm_bridge_connector.
