[Why]
Enable the Panel Replay if eDP panel and ASIC support.
(prioritize Panel Replay over PSR)
[How]
- Setup the Panel Replay config during the device init
(prioritize Panel Replay over PSR).
- Separate the Replay init function into two functions
amdgpu_dm_link_setup_replay() and amdgpu_dm_set_replay_caps()
to fix the issue in the earlier commit that cause PSR and Replay
enabled at the same time.

This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5.
Since, it causes a regression in which eDP displays with PSR support,
but no Replay support (Sink support <= 0x03), fail to enable PSR and
consequently all IGT amd_psr tests fail. So, revert this until a more
suitable fix can be found.
This got brought back accidently with the backmerge.

this can cause the suspend to fail under memory pressure. Introduce
a new phase that IP blocks can use to allocate memory before suspend

This reverts commit 80c6d6804f31451848a3956a70c2bcb1f07cfcb0.
The orignal commit was intended as a workaround to prevent underflow and
flickering when using one normal monitor and the other high refresh rate
monitor (> 120Hz).
This patch is being reverted in favour of a software solution to enable
SubVP+DRR

[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.
Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.
If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:
amdgpu.dcfeaturemask=0x200

[Why]
For optimal power savings on panels that can support it.
This was previously left disabled by default because of issues with
compositors that do not pageflip and scan out directly to the
frontbuffer.
For these compositors we now have detection methods that wait for x
number of pageflips after a full update - triggered by a buffer or
format change typically.
This may introduce bugs or new cases not tested by users so this is
only currently targeting newer DCN.
[How]
Add code in DM to set PSR state by default for newer DCN while falling
back to the feature mask for older.
Add a global debug flag that can be set to disable it for either.
