[00/17] Add support for CDM over DP

Message

The Chroma Down Sampling (CDM) block is a hardware component in the DPU
pipeline that includes a CSC block capable of converting RGB input from
the DPU to YUV data.

This block can be used with either HDMI, DP, or writeback interfaces.
This series adds support for the CDM block to be used with DP in
YUV420 mode format.

This series allows selection of the YUV420 format for monitors which support
certain resolutions only in YUV420 thus unblocking the validation of many
other resolutions which were previously filtered out if the connector did
not support YUV420.

This was validated using a DP connected monitor requiring the use of
YUV420 format.

This series currently works as-is. But it was also validated to function on
top of in the case of future integration:
