Add GSC support for XeHP SDV and DG2 platforms.

The series includes changes for the mei driver:
- add ability to use polling instead of interrupts
- add ability to use extended timeouts
- setup extended operational memory for GSC

The series includes changes for the i915 driver:
- allocate extended operational memory for GSC
- GSC on XeHP SDV offsets and definitions

Greg KH, please review and ACK the MEI patches.
We are pushing these patches through gfx tree as
the auxiliary device belongs there.

V2: rebase over merged DG1 series and DG2 enablement patch,
    fix commit messages

V3: rebase over latest tip

V4: add missed changelog in pxp dbugfs patch

V5: rebase over latest tip
    fix changelog in pxp dbugfs patch
    put HAX patch last to the ease of merging

Alexander Usyskin (5):
  drm/i915/gsc: add slow_fw flag to the mei auxiliary device
  drm/i915/gsc: add slow_fw flag to the gsc device definition
  drm/i915/gsc: add GSC XeHP SDV platform definition
  mei: gsc: wait for reset thread on stop
  mei: extend timeouts on slow devices.

Daniele Ceraolo Spurio (1):
  HAX: drm/i915: force INTEL_MEI_GSC on for CI

Tomas Winkler (5):
  mei: gsc: use polling instead of interrupts
  mei: mkhi: add memory ready command
  mei: gsc: setup gsc extended operational memory
  mei: debugfs: add pxp mode to devstate in debugfs
  drm/i915/gsc: allocate extended operational memory in LMEM

Vitaly Lubart (3):
  drm/i915/gsc: skip irq initialization if using polling
  mei: bus: export common mkhi definitions into a separate header
  mei: gsc: add transition to PXP mode in resume flow

You did more than just this from v4 to v5 :(

It's as if you want to make it hard to review these...

I just checked the code and it looks the same to me.

well, yeap, changing the order of other commits during the rebase
was not mentioned. So we don't know the reason...

But at least now the HAX is the last patch what makes more sense.

But I don't believe this should block the review and require a v6
just to add this comment in the cover letter, or it should?

Rodrigo.
