[PATCH 12/28] drm/amd/display: Set VSC SDP Colorimetry same way for MST and SST

[Hamza Mahfooz]

From: Harry Wentland <harry.wentland at amd.com>

The previous check for the is_vsc_sdp_colorimetry_supported flag
for MST sink signals did nothing. Simplify the code and use the
same check for MST and SST.
