drm/amd/display: Enable colorspace property for MST connectors
[ Upstream commit 8195979d2dd995d60c2663adf54c69c1bf4eadd1 ]
MST colorspace property support was disabled due to a series of warnings
that came up when the device was plugged in since the properties weren't
made at device creation. Create the properties in advance instead.
