Subject: [PATCH] ACPICA: Add PRMT module header to facilitate parsing

commit 9f8c7baedabc9693fbd7890f8fda40578bde4f73 upstream.

ACPICA commit bd46cb07e614fd85ea69e54c1f6f0ae0a5fb20ab

This structure is used in to parse PRMT in other Operating Systems
that relies on using subtable headers in order to parse ACPI tables.
Although the PRMT doesn't have "subtables" it has a list of module
information structures that act as subtables.
