drm/amd/display: Fix system hang while resume with TBT monitor
[Why]
Connected with a Thunderbolt monitor and do the suspend and the system
may hang while resume.
The TBT monitor HPD will be triggered during the resume procedure
and call the drm_client_modeset_probe() while
struct drm_connector connector->dev->master is NULL.
It will mess up the pipe topology after resume.
[How]
Skip the TBT monitor HPD during the resume procedure because we
currently will probe the connectors after resume by default.

drm/amd/display: Clip rect size changes should be full updates
[Why]
In cases where an MPO plane is being dragged around partially off-screen,
it is possible to get a flip where the only scaling parameters to change
are the clip rect size and position. Currently, clip rect size changes
are considered medium updates, which can result in the clip rect being used
for HW programming being larger than the clip rect that was used for the
last DML validation. This can lead to mismatches in different parts of the
pipe and can result in a p-state hang.
[How]
- consider clip rect size changes scaling changes, therefore full updates
- refactor get_scaling_info_update_type for clarity
- remove clip_size_change update flag
Clip rect size changes were previously demoted from full updates as an
optimization when the MPO + ODM policy changed to always pre-allocate MPO
pipes, but it created the issue described above. Personally testing this
use case, the performance feels fine with full update spam, and we expect
this is a fairly infrequent use case. If the performance needs to be
optimized in the future, consider reworking the entire update type logic
to run a DML pass and determine the update type based on what DML says
will actually change.

drm/amdgpu: sync to KFD fences before clearing PTEs
This patch tries to solve the basic problem we also need to sync to
the KFD fences of the BO because otherwise it can be that we clear
PTEs while the KFD queues are still running.

drm/amd/display: handle nulled pipe context in DCE110's set_drr()
As set_drr() is called from IRQ context, it can happen that the
pipe context has been nulled by dc_state_destruct().
Apply the same protection here that is already present for
dcn35_set_drr() and dcn10_set_drr(). I.e. fetch the tg pointer
first (to avoid a race with dc_state_destruct()), and then
check the local copy before using it.

Currently amdgpu takes backlight caps provided by the ACPI tables
on systems as is. If the firmware sets maximums that are too low
this means that users don't get a good experience.
To avoid having to maintain a quirk list of such systems, do a sanity
check on the values. Check that the spread is at least half of the
values that amdgpu would use if no ACPI table was found and if not
use the amdgpu defaults.

1) We did linear/non linear transition properly long ago
2) We used that path to handle SystemDisplayEnable
3) We fixed a SystemDisplayEnable inability to fallback to passive by
impacting the transition flow generically
4) AFMF later relied on the generic transition behavior
Separating the two flows to make (3) non-generic is the best immediate
coarse of action.
DC can discern SSAMPO3 very easily from SDE.
