Nicholas Kazlauskas 58aa1c50e5 drm/amd/display: Use vblank control events for PSR enable/disable 
[Why]
PSR can disable the HUBP along with the OTG when PSR is active.

We'll hit a pageflip timeout when the OTG is disable because we're no
longer updating the CRTC vblank counter and the pflip high IRQ will
not fire on the flip.

In order to flip the page flip timeout occur we should modify the
enter/exit conditions to match DRM requirements.

[How]
Use our deferred handlers for DRM vblank control to notify DMCU(B)
when it can enable or disable PSR based on whether vblank is disabled or
enabled respectively.

We'll need to pass along the stream with the notification now because
we want to access the CRTC state while the CRTC is locked to get the
stream state prior to the commit.

Retain a reference to the stream so it remains safe to continue to
access and release that reference once we're done with it.

Enable/disable logic follows what we were previously doing in
update_planes.

The workqueue has to be flushed before programming streams or planes
to ensure that we exit out of idle optimizations and PSR before
these events occur if necessary.

To keep the skip count logic the same to avoid FBCON PSR enablement
requires copying the allow condition onto the DM IRQ parameters - a
field that we can actually access from the worker.
