[PATCH v13 0/4] Support PMT features in Xe

["Michael J. Ruhl" <michael.j.ruhl@intel.com>]

Battlemage has the Intel Platform Monitoring Technology (PMT)
feature available, but not in the "standard" (pci endpoint) way.

Add support to the vsec and Xe drivers to allow access to the PMT space
for the BMG devices.

The intel_vsec_register() function allows drivers to provide telemetry
header information (usually found at probe time), to allow the PMT
driver to probe the telemetry features.

Battlemage has a shared memory area (selected by index), so a callback
function is required to access the appropriate PMT data.

Note: patches 1 - 3 will be merged through the platform-drivers-x86
      tree.  This submission is for DRM CI.
V2:
  Re-worked DG2 support patches using a base_adjust rather than a
  quirk.
  Updated GUID decode, for correct decode.
v3:
  Fixed a documentation issue for the pmt struct.
v4:
  Fixed a documentation issue in the xe_vsec.c module
v5:
  Addressed review comments for patch 4 (Xe driver)
  Add r/b for the first three patches
v6:
  Added kernel doc to moved data structure
  Added required include files
  Correct usage for FIELD_PREP()/FIELD_GET()
  Whitespace clean up
  Removed unnecessary type cast
v7:
  Commit message updates
v8:
  Added some r/b (patch 2 and 3).
  Updated kernel doc patch 2 (priv_data) patch 5 (base_adjust)
v9:
  Add r/b for the Xe driver patches
v10:
  Use the mutex guard feature
  Use the xe_pm_runtime_get_if_active() return value correctly
  Add r/b from Ilpo
  Deferred DG2 patches for the future
v11:
  add include for cleanup.h
v12:
  use default clause in switch
  rename OFFSET to OFFSET_BASE
v13:
  updated mmio usage to use the current Xe mmio API
