drm/amd/display: Match actual state during S3 resume.
During system suspend, we:
1. Cache a duplicate of the current DRM atomic state, which calls hooks
to duplicate our internal states.
2. Call hooks to disable all functionalities.
3. System suspended.
During resume, we attempt to restore the cached state. However, our
interal states are now stale, since step 1 was done before step 2.
i.e. our cached state does not reflect the disabled nature of things.
This change resolves that by destroying all relevant states to reflect
the actual state during resume.

However it seems the HDMI controller will modify some of the bits

Even though the components framework can handle duplicate entries,
the extra entries cause a lot more debug messages to be generated,
which would be confusing to developers not familiar with our driver

Instead, we can scan the relatively small queue and check if the
component to be added is already queued up. Since the display
pipelines are symmetrical (not considering the third display
pipeline on the A80), and we add components level by level, when
we get to the second instance at the same level, any shared downstream
components would already be in the queue.

Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
Most notable addition this time is the support for the GPU performance
counters by Christian. This has been in the making for some time and it
has matured a lot. Since this is adding UAPI, the corresponding WIP
userspace can be found at [1] mesa/libdrm repos. I expect that
Christian sends out the final userspace patches for this once you have
pulled the kernel bits.
Philipp optimized the probe path, so etnaviv gets out of the way for
systems that want to boot real quick.
I've done mostly cleanups, disentangling etnaviv from the IOMMU API,
with some MMUv1 optimizations on the way.

drm/vc4: Move the DSI clock divider workaround closer to the clock call.
We want the adjusted_mode->clock to be the actual clock we're
expecting to program, so that consumers see the right values for clock
and vrefresh.
