disp: msm: dp: add colorspace property for MSM DP

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.
