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. David E.
