[Intel-gfx] [PULL] drm-intel-fixes

[Joonas Lahtinen]

Hi Dave & Daniel,

-rc1 required the usual juggling to get baseline from CI.
Needed to temporarily apply this fixup to drm-intel-fixes:
"ext4: mballoc: Use this_cpu_read instead of this_cpu_ptr"

For display side, fix for TypeC interrupt storm detection. Fixes to
TypeC, DDI and MST hardware register programming.

On GT side, fixes into timeslicing and missing workarounds after GPU
reset.

A couple of build time warning fixes.

CI results are partially back online (hopefully more will come shortly):

https://intel-gfx-ci.01.org/tree/drm-intel-fixes/combined-alt.html?

CI_DIF_483 - With the ext4 fix
CI_DIF_484 - This PR, no ext4 fix => extra warnings

Regards, Joonas

PS. I'll be away for the next 4 weeks, so expect to see the following
drm-intel-fixes PRs from Jani and Rodrigo.
