[Why]

Enabling Z10 optimizations allows DMUB to disable the OTG during PSR
link-off. This theoretically saves power by putting more of the display
hardware to sleep. However, we observe that with PSR SU, it causes
visual artifacts, higher power usage, and potential system hang.

This is partly due to an odd behavior with the VStartup interrupt used
to signal DRM vblank events. If the OTG is toggled on/off during a PSR
link on/off cycle, the vstartup interrupt fires twice in quick
succession. This generates incorrectly timed vblank events.
Additionally, it can cause cursor updates to generate visual artifacts.

Note that this is not observed with PSR1 since PSR is fully disabled
when there are vblank event requestors. Cursor updates are also
artifact-free, likely because there are no selectively-updated (SU)
frames that can generate artifacts.

[How]

A potential solution is to disable z10 idle optimizations only when fast
updates (flips & cursor updates) are committed. A mechanism to do so
would require some thoughtful design. Let's just disable idle
optimizations for PSR2 for now.

[Why&How]

Several transitions were fixed that will allow Dynamic ODM and MPO
transitions to be supported on DCN32.

1) Due to resource limitations, in certain scenarios that require an MPO
plane to be split, the features cannot be combined with the current
policy. This is due to unsafe transitions being required (OPP instance
per MPCC being switched on active pipe is not supported by DCN), to
support the split plane with ODM active as it moves across the viewport.
Dynamic ODM will now be disabled when MPO is required.

2) When exiting MPO and re-entering ODM, DC assigns an inactive pipe for
the next ODM pipe, which under previous power gating policy would result
in programming a gated DSC HW block. New policy dynamically
gates/un-gates DSC blocks when Dynamic ODM is active to support

transitions on DCN32 only.

3) Entry and exit from 3 plane MPO and Dynamic ODM requires a minimal
transition so that all pipes which require their MPCC OPP instance to
be changed have a full frame to be disabled before reprogramming. To
solve this, the Dynamic ODM policy now utilizes minimal state
transitions when entering or exiting 3 plane scenarios.

4) Various fixes to DCN32 pipe merge/split algorithm to support Dynamic
ODM and MPO transitions.

In summary, this commit fixes various transitions to support ODM->MPO
and MPO->ODM.

[Why&How]
Phantom pipes are not programmed fully to hardware and hence we should
not expect a flip completion.

[Why]
For individual feature testing, PMFW may not report all clock
values back. Driver will default them to 0 but this will
cause the BB table to be skipped and default to one state
with max clocks.

[How]
Add helper function to scan through initial clock values and
populate them with default clock limits so that BB table
can be built.
Add dpm_enabled flag to check when DPM is not enabled and
to trigger helper function.
