drm/amd/display: Program VSC SDP colorimetry for all DP sinks >= 1.4

commit 9e61ef8 upstream.

In order for display colorimetry to work correctly on DP displays
we need to send the VSC SDP packet. We should only do so for
panels with DPCD revision greater or equal to 1.4 as older
receivers might have problems with it.
