drm/amd/display: Port DCN30 420 logic to DCN32
[Why]
420 modes are limited by FMT buffer width of 4096
which requires multi-pipe support in form of ODM
combine. If 420 modes have greater HActive than
4096, the DML logic should accomodate whether
it should be rejected, or ODM combine 2:1 or 4:1
is triggered accordingly.
[How]
FMT Buffer limit of 4096 in DCN32. Force ODM
combine depending on HActive and FMT Buffer limit.
Reject modes if TMDS 420 and above 4096.
