ratios, prepare the DP driver for the same by removing the usage of
the compression ratio enum.

Add support to pass extended capability information to the DPCD
debugfs node. This will help to validate features like VSC support
using debugfs node.
Usage will be the same as before and the change will automatically
detect the presence of extended capability field and expect
additional bytes of information.

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.
