drm/amd/display: Workaround wrong HDR colorimetry with some receivers
[Why]
Some scalers do not pick up color space updates unless the DP link
is disabled/re-enabled which can result in incorrect/washed out
HDR colors in some cases.
[How]
Call set_dpms_on to disable the link, re-train and re-enable with the
updated output color space.
