drm/amd/display: Fix underflow when playing 8K video in full screen mode

Browse Source 
[Why&How]
Flickering observed while playing 8k HEVC-10 bit video in full screen
mode with black border. We didn't support this case for subvp.
Make change to the existing check to disable subvp for this corner case.
