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) David E.
