drm/xe/display: Flush DMC wakelock release work on runtime suspend
We currently are not calling display runtime suspend functions when
D3cold is not allowed. Because of that, we end up not disabling dynamic
DC states (and do not go to DC9). With dynamic DC states enabled, we
will also have DMC wakelock enabled. Since we use a delayed work to
release the DMC wakelock, the work might get executed a little too late
(after the PCI device has been put to D3hot) and we get a timeout
warning ("DMC wakelock release timed out") because the MMIO for
releasing the wakelock will be invalid after that point.
To fix that, make sure we flush the release work at the end of
xe_display_pm_runtime_suspend_late(). We can do that unconditionally
because, if there is no pending work, that turns into a no-op.

drm/i915/color: Stop using non-posted DSB writes for legacy LUT
DSB LUT register writes vs. palette anti-collision logic
appear to interact in interesting ways:
- posted DSB writes simply vanish into thin air while
anti-collision is active
- non-posted DSB writes actually get blocked by the anti-collision
logic, but unfortunately this ends up hogging the bus for
long enough that unrelated parallel CPU MMIO accesses start
to disappear instead
Even though we are updating the LUT during vblank we aren't
immune to the anti-collision logic because it kicks in briefly
for pipe prefill (initiated at frame start). The safe time
window for performing the LUT update is thus between the
undelayed vblank and frame start. Turns out that with low
enough CDCLK frequency (DSB execution speed depends on CDCLK)
we can exceed that.
As we are currently using non-posted writes for the legacy LUT
updates, in which case we can hit the far more severe failure
mode. The problem is exacerbated by the fact that non-posted
writes are much slower than posted writes (~4x it seems).
To mititage the problem let's switch to using posted DSB
writes for legacy LUT updates (which will involve using the
double write approach to avoid other problems with DSB
vs. legacy LUT writes). Despite writing each register twice
this will in fact make the legacy LUT update faster when
compared to the non-posted write approach, making the
problem less likely to appear. The failure mode is also
less severe.
This isn't the 100% solution we need though. That will involve
estimating how long the LUT update will take, and pushing
frame start and/or delayed vblank forward to guarantee that
the update will have finished by the time the pipe prefill
starts...

drm/i915/dsb: Don't use indexed register writes needlessly
Turns out the DSB indexed register write command has
rather significant initial overhead compared to the normal
MMIO write command. Based on some quick experiments on TGL
you have to write the register at least ~5 times for the
indexed write command to come out ahead. If you write the
register less times than that the MMIO write is faster.
So it seems my automagic indexed write logic was a bit
misguided. Go back to the original approach only use
indexed writes for the cases we know will benefit from
it (indexed LUT register updates).
Currently we shouldn't have any cases where this truly
matters (just some rare double writes to the precision
LUT index registers), but we will need to switch the
legacy LUT updates to write each LUT register twice (to
avoid some palette anti-collision logic troubles).
This would be close to the worst case for using indexed
writes (two writes per register, and 256 separate registers).
Using the MMIO write command should shave off around 30%
of the execution time compared to using the indexed write
command.

drm/i915/dpt: Evict all DPT VMAs on suspend
Currently intel_dpt_resume() tries to blindly rewrite all the
PTEs for currently bound DPT VMAs. That is problematic because
the CPU mapping for the DPT is only really guaranteed to exist
while the DPT object has been pinned. In the past we worked
around this issue by making DPT objects unshrinkable, but that
is undesirable as it'll waste physical RAM.
Let's instead forcefully evict all the DPT VMAs on suspend,
thus guaranteeing that intel_dpt_resume() has nothing to do.
To guarantee that all the DPT VMAs are evictable by
intel_dpt_suspend() we need to flush the cleanup workqueue
after the display output has been shut down.
And for good measure throw in a few extra WARNs to catch
any mistakes.

drm/i915/display: identify discrete graphics
Identify discrete graphics separately in display, using the platform
group mechanism. This enables dropping the dependency on i915_drv.h
IS_DGFX() from display code.
Start grouping platform groups separately in INTEL_DISPLAY_PLATFORMS()
in anticipation of more groups to come.

drm/i915/hdcp: Fix when the first read and write are retried
Make sure that the first read/write in hdcp2_authentication_key_exchange
are only retried when we have either DP/DPMST encoder connected,
since we do this to give docks and dp encoders some extra time to
get their HDCP DPCD registers ready only for DP/DPMST encoders as
this issue is only observed here no need to burden other encoders
with extra retries as this causes the HDMI connector to have some
other timing issue and fails HDCP authentication.
--v2
-Add intent of patch [Chaitanya]
-Add reasoning for loop [Jani]
-Make sure we forfiet the 50ms wait for non DP/DPMST encoders.
--v3
-Remove the is_dp_encoder check [Jani/Chaitanya]
-Make the commit message more clearer [Jani]
