Subject: drm/amd/display: Update DP HPO MSA with colorimetry from test request
Git-commit: 81df7271688cf04a502e3bbd19d0395a986a89e1
Patch-mainline: v6.7-rc1
References: jsc#PED-3527 jsc#PED-5475 jsc#PED-6068 jsc#PED-6070 jsc#PED-6116 jsc#PED-6120 jsc#PED-5065 jsc#PED-5477 jsc#PED-5511 jsc#PED-6041 jsc#PED-6069 jsc#PED-6071
[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.
