Add code to parse the arm64 specific MPAM table, looking up the cache level from the PPTT and feeding the end result into the MPAM driver. This happens in two stages. Platform devices are created first for the MSC devices. Once the driver probes it calls acpi_mpam_parse_resources() to discover the RIS entries the MSC contains. For now the MPAM hook mpam_ris_create() is stubbed out, but will update the MPAM driver with optional discovered data about the RIS entries.

Arm Generic Diagnostic Dump and Reset Device Interface (AGDI) is
|
|
a standard that enables issuing a non-maskable diagnostic dump and
|
|
reset command.
|
|
|
|
If set, the kernel parses AGDI table and listens for the command.
