The drm_bridge "supported_formats" member stores a bitmask of supported HDMI output formats if the bridge is in fact an HDMI bridge.
However, until now, the synopsys dw-hdmi-qp driver did not set this member in the bridge it creates. Set it based on the platform data's supported_formats member, and default to BIT(HDMI_COLORSPACE_RGB) if it's absent, which preserves the previous behaviour.
