ACPICA: iASL/Disassembler: Add support for MTMR table

MTMR table is used in the recent ACPI BIOS enabled Intel MID
platforms.  The format of this table has been defined in the
"Simple Firmware Interface Specification" except it uses GAS
instead of 64-bit values for address fields.  This patch introduces
MTMR table support into ACPICA.  Lv Zheng.
