  KVM CLX ACPI HMAT table support

Status in linux package in Ubuntu:

Bug description:
  ACPI HMAT table support : HMAT is a new ACPI table that records the
  performance parameter of memory, so MCDRAM (or next gen HBM2) can be
  described well by this table. We need to support this table in kernel
  and qemu so that guest can get and parse this table then to find where
  the high-performance memory is.

  Heterogeneous Memory Attribute Table (HMAT) describes the memory attributes, 
such as memory
   side cache attributes and bandwidth and latency details, related to the 
System Physical Address
   (SPA) Memory Ranges. The software is expected to use this information as 
hint for optimization.

  HMAT is defined in ACPI 6.2: 5.2.27 Heterogeneous Memory Attribute Table
