src/acpi: Add initial support for HMAT
Add initial HMAT (Heterogeneous Memory Attribute Table) support based
on ACPI spec 6.4 section 5.2.27.
Add functions to create HMAT table (revision 2) and create HMAT Memory
Proximity Domain Attribute (MPDA) Structure.
TESTED=Simulated HMAT table creation on OCP DeltaLake server, dumped
the HMAT table and exmained the content. HMAT table and one MPDA
structure are added.
OCP Delatake server is based on Intel CooperLake Scalable Processor
which does not support CXL (Compute Express Link). Therefore solution
level testing is not done.
