917bda9ab1 Merge drm/drm-next into drm-intel-next 
Sync drm-intel-next with v6.0-rc as well as recent drm-intel-gt-next.

Since drm-next does not have commit f0c70d41e4e8 ("drm/i915/guc: remove
runtime info printing from time stamp logging") yet, only
drm-intel-gt-next, will need to do that as part of the merge here to
build.

b183db8f47 drm/i915: Skip wm/ddb readout for disabled pipes 
The stuff programmed into the wm/ddb registers of planes
on disabled pipes doesn't matter. So during readout just
leave our software state tracking for those zeroed.

This should avoid us trying too hard to clean up after
whatever mess the VBIOS/GOP left in there. The actual
hardware state will get cleaned up if/when we enable
the pipe anyway.

08e9505fa8 drm/i915/glk: ECS Liva Q2 needs GLK HDMI port timing quirk 
The quirk added in upstream commit 90c3e2198777 ("drm/i915/glk: Add
Quirk for GLK NUC HDMI port issues.") is also required on the ECS Liva
Q2.

Note: Would be nicer to figure out the extra delay required for the
retimer without quirks, however don't know how to check for that.
