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
    reorder patches in the series

V6: change prefix from 'drm/i915/gsc:' to 'mei' in patch:
        mei: add slow_fw flag to the mei auxiliary device
    Address following checkpatch warnings:
        CHECK:PREFER_KERNEL_TYPES: Prefer kernel type 'u32' over 'uint32_t'
        FILE: drivers/misc/mei/mkhi.h:54:
        +	uint32_t flags; 
        
        -:51: CHECK:UNNECESSARY_PARENTHESES: Unnecessary parentheses around 'cldev->bus->pxp_mode != MEI_DEV_PXP_INIT'
        #51: FILE: drivers/misc/mei/bus-fixup.c:257:
        +	if (!cldev->bus->fw_f_fw_ver_supported &&
        +	    (cldev->bus->pxp_mode != MEI_DEV_PXP_INIT)
    
    Remove some spurious code formatting changes in:
    drm/i915/gsc: allocate extended operational memory in LMEM


Alexander Usyskin (5):
  mei: 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):

Please wait until after -rc1 is out, my trees are closed for new work at
this point in time, and so should the gfx tree :)
