4ce4fe2720 drm/amdgpu/vcn: use per instance callbacks for idle work handler
Use the vcn instance power gating callbacks rather than
the IP powergating callback.  This limits power gating to
only the instance in use rather than all of the instances.

- update the sysfs reset mask to the `late_init` stage to ensure that the SMU  initialization
     and capability setup are completed before checking the SDMA reset capability.
- For IP versions 9.4.3 and 9.4.4, enable per-queue reset if the MEC firmware version is at least 0xb0 and PMFW supports queue reset.
- Add a TODO comment for future support of per-queue reset for IP version 9.5.0.

This change ensures that per-queue reset is only enabled when the MEC and PMFW support it.

[Why]

So when amdgpu_irq_gpu_reset_resume_helper() reprograms all of the IRQs,
HPD gets disabled.

8adeff83a3 drm/amd/display: stop DML2 from removing pipes based on planes
[Why]
Transitioning from low to high resolutions at high refresh rates caused grey corruption.
During the transition state, there is a period where plane size is based on low resultion
state and ODM slices are based on high resoultion state, causing the entire plane to be
contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane,
causing an underflow since the pixel rate for the higher resolution cannot be supported on
one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice
with no plane. This is possible to do without negative consequences because pipes can now
take the minimum viewport and draw with zero recout size, removing the need to have the
pipe turned off.

[How]
In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by
the plane. This prevents the pipes for those ODM slices from being freed.
