[PATCH v4 05/10] drm/bridge: dw-hdmi-qp: Set bridge supported_formats

[Nicolas Frattaroli <nicolas.frattaroli@collabora.com>]

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.
