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 David E.
