[PATCH 17/22] drm/amd/display: Fix display corruption w/ VSR enable

[brichang]

From: Ilya Bakoulin <Ilya.Bakoulin at amd.com>

[Why]
Brief corruption is observed on hotplug/unplug with certain display
configurations when VSR is enabled.

[How]
Work around the issue by avoiding 2to1 ODM when stream plane_count is 0.
