ACPICA: infrastructure: Add new DMT_BUF types and shorten a long name

ACPICA commit b8713f71b4023a0396fe61503bbbf5226e5eed1b

Some ERDT subtables have 11 and 24 byte reserved fields.

Add the ACPI_DMT_BUF11 and ACPI_DMT_BUF24 types to describe these reserved
fields in struct acpi_dmtable_info structures.

Shorten the ACPI_SUBTABLE_HEADER_16 name to ACPI_SUBTBL_HDR
