drm/amd/display: Revert Remove pixle rate limit for subvp

Browse Source 
This reverts commit 340383c734 ("drm/amd/display: Remove pixle rate
limit for subvp")

[why]
The original commit causes a regression when subvp is applied
on ODM required 8k60hz timing. The display shows black screen
on boot. The issue can be recovered with hotplug. It also causes
MPO to fail. We will temprarily revert this commit and investigate
the root cause further.
