src/intel/xeon_sp: add hardware error support (HEST)

Browse Source 
This patch adds the ACPI hardware error source table (HEST) support.
This involves a few different parts: (1) The ACPI HEST table which is filled
with the appropriate fields (2) Reserved memory which is used by runtime
SW to provide error information. OS will not accept a HEST table with
this memory set to 0.

The ASL code to enable APEI bit will be submitted in a separate patch.

Tested on DeltaLake mainboard with following options enabled
SOC_INTEL_XEON_RAS

After boot to Linux, the following will show in dmesg:
HEST: Table parsing has been initialized
