Add the colorspace property for DP controller for MSM. Also, change the default method to send the colorimetry information to the sink from MISC bits of MSA to VSC SDP packets if the sink supports it. This helps to avoid dynamic switches between the packet types for sending the colorimetry information during BT2020 and DCI-P3 use-cases.
