9cb1547891 drm/i915/dp_mst: Work around Thunderbolt sink disconnect after SINK_COUNT_ESI read 
Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT
link may get disconnected inadvertently if the SINK_COUNT_ESI and the
DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX
transaction. Work around the issue by reading these registers in
separate transactions.

The issue affects MTL+ platforms and will be fixed in the DP-in adapter
firmware, however releasing that firmware fix may take some time and is
not guaranteed to be available for all systems. Based on this apply the
workaround on affected platforms.

See HSD #13013007775.

a92e390e0d drm/i915/dp_mst: Use the correct connector while computing the link BPP limit on MST 
Atm, on an MST link in DSC mode
intel_dp_compute_config_link_bpp_limits() calculates the maximum link
bpp limit using the MST root connector's DSC capabilities. That's not
correct in general: the decompression could be performed by a branch
device downstream of the root branch device or the sink itself.

Fix the above by passing to intel_dp_compute_config_link_bpp_limits()
the actual connector being modeset, containing the correct DSC
capabilities.

0f2ab6a773 drm/i915/irq: move i915->irq_lock to display->irq.lock 
Observe that i915->irq_lock is no longer used to protect anything
outside of display. Make it a display thing.

This allows us to remove the ugly #define irq_lock irq.lock hack from xe
compat header.

Note that this is slightly more subtle than it first looks. For i915,
there's no functional change here. The lock is moved. However, for xe,
we'll now have *two* locks, xe->irq.lock and display->irq.lock. These
should protect different things, though. Indeed, nesting in the past
would've lead to a deadlock because they were the same lock.

With the i915 references gone, we can make a handful more files
independent of i915_drv.h.

Commit 1c56e9a398 ("drm/i915/dp: Get optimal link config to have best
compressed bpp") tries to find the best compressed bpp for the
link. However, it iterates from max to min bpp on display 13+, and from
min to max on other platforms. This presumably leads to minimum
compressed bpp always being chosen on display 11-12.

Iterate from high to low on all platforms to actually use the best
possible compressed bpp.
