The HDMI block is currently hardcoded to expect RGB output from the display controller. However, the VOP in some SoCs are capable of YCbCr output to the HDMI block. Read the negotiated bus format from the bridge state and propagate it to the CRCT state in form of output mode and bus format. Treat the format MEDIA_BUS_FMT_FIXED as RGB888 and reject any unsupported formats. This has no inpact until dw-hdmi bridge is fully converted to a HDMI bridge and also adds support for the "color format" connector property.
