drm/amd/display: Cap DML2.1 vmin ODM combine at 2:1 for eDP
[Why]
Currently in DML2.1, by design, the DPMs are unpinned when optimizing
for Vmin PMO. This leads to an issue on DCN42 on specific panels (e.g. 4k144 eDP)
where ODM4:1 is applied unexpectedly, which affects the urgent bandwidth required,
raises DCFCLK to DPM1, and thus blocks Z8.
[How]
Clamp the ODM combine limit to 2 for eDP streams directly in
