DG2 and Battlemage have 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 DG2 and 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.
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)
