[PATCH 1/2] drm/amd/amdgpu: Use IP discovery data to determine VCN enablement instead of MMSCH

From: Bokun Zhang In the past, we use MMSCH to determine whether a VCN is enabled or not. This is not reliable since after a FLR, MMSCH may report junk data. It is better to use IP discovery data. Signed-off-by: Bokun Zhang Signed-off-by: Peng Ju Zhou ---
