[why]
During minimal transition commit, the base state could be freed if it is current state.
This is because after committing minimal transition state, the current state will be
swapped to the minimal transition state and the old current state will be released.
the release could cause the old current state's memory to be freed. However dc
will derefernce this memory when release minimal transition state. Therefore, we
need to retain the old current state until we release minimal transition state.

[Why]
Disabling stream encoder invokes a function that no longer exists
in bring-up.
[How]
Check if the function declaration is NULL in disable stream encoder.

From: Wenjing Liu <wenjing.liu(a)amd.com>
This reverts commit 6cf00f4c4d5c ("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.

From: Leo Ma <hanghong.ma(a)amd.com>
[Why]
When mode switching is triggered there is momentary noise visible on
some HDMI TV or displays.
[How]
Wait for 2 frames to make sure we have enough time to send out AV mute
and sink receives a full frame.
