drm/amd/display: Check if PSR enabled when entering MALL

[Description]
- When attempting to enter MALL SS when a PSR panel
is connected, we have to check that the PSR panel
has already entered PSR because the vsync interrupt
call is per display index (can be called for the
non-PSR panel first)
- Also don't override link settings when programming
phantom stream (main and phantom pipe share the same link)
