[PULL] drm-intel-fixes

[Joonas Lahtinen]

Hi Dave & Daniel,

Happy New Year, now back from the holiday break.

A bunch of important fixes. Further fixes for the power/perf
regressions caused by the past security fixes. Then fix for
user reported GPU hang regression. Revert to avoid screen flicker
caused by HDA audio. Then missing two W/A and uninitialized uAPI
variable fix.

There's one further fix which I didn't include in this PR as the
CI results won't make it in time. So at least that will be in next
weeks PR.

Regards, Joonas
