[PATCH 10/25] drm/amd/display: Update DP HPO MSA with colorimetry from test request

[Hersen Wu]

From: George Shen <george.shen at amd.com>

[Why]
Some DP link layer tests request a different colorimetry than the
default one that is used. Currently, our test automation logic does not
update the MSA with the test request value for DP HPO case.

[How]
Update HPO MSA colorimetry with test automation request value.
