drm/display: bridge_connector: Use HDMI color format for HDMI conns
For bridge connectors which contain an HDMI bridge at some stage, the
HDMI state helpers' format selection logic should be involved.
Add an implementation for the drm_bridge_funcs color_format function,
which translates from the HDMI state's output format to a connector
format for bridge connectors involving an HDMI bridge, but return the
connector state's color_format member unchanged otherwise.
