drm/amd/display: Set max vratio for prefetch to 7.9 for YUV420 MPO
[Description]
- Single 4K60 playing YUV420 MPO video blocks P-State because
the required VRatio for prefetch is too high (luma plane for
YUV420 is 1bpe, so swath height is 16 and prefetch requires
more lines)
- Allow max vratio per plane to be 7.9 for single display YUV420
MPO video cases
- Ensure that global vratio prefetch (i.e. total prefetch BW vs.
total active bandwidth) does not excited 4.0
