x86: run timers when populating Dom0's P2M table
When booting Dom0 with huge amounts of memory, and/or memory accesses
being sufficiently slow (due to NUMA effects), and the ACPI PM timer
or a high frequency HPET being used, the time it takes to populate the
M2P table may significantly exceed the overflow time of the platform
timer, screwing up time management to the point where Dom0 boot fails.
