[PATCH 4/7] drm/amd/display: Temporary Disable MST DP Colorspace Property

[Aurabindo Pillai]

From: Fangzhi Zuo <jerry.zuo at amd.com>

Create MST colorsapce property for downstream device would trigger
warning message "RIP: 0010:drm_mode_object_add+0x8e/0xa0 [drm]"

After driver is loaded and drm device is registered, create
dp colorspace property triggers warning storm at
WARN_ON(!dev->driver->load && dev->registered && !obj_free_cb);

Temporary disabling MST dp colorspace property for now.
