From: Kan Liang <Kan.liang@intel.com>

Current DTLB load/store miss events (0x608/0x649) only counts 4K,2M and
4M page size.
Need to extend the events to support any page size (4K/2M/4M/1G).

The complete DTLB load/store miss events are
DTLB_LOAD_MISSES.WALK_COMPLETED		0xe08
DTLB_STORE_MISSES.WALK_COMPLETED	0xe49
