drm/bridge-connector: Sync supported_formats with computed ycbcr_420_allowed

Browse Source 
The case of having an HDMI bridge in the pipeline which advertises
YUV420 capability via its ->supported_formats and a non-HDMI one that
didn't enable ->ycbcr_420_allowed, is incorrectly handled because
supported_formats is passed as is to the helper initializing the HDMI
connector.

Ensure HDMI_COLORSPACE_YUV420 is removed from the bitmask passed to
drmm_connector_hdmi_init() when connector's ->ycbcr_420_allowed flag
ends up not being set.
