[IA64] Disable ACPI SRAT,SLIT table of dom0.

  On some ia64 NUMA machine, we cannot boot dom0.
  This issue is caused by different infomation LSAPIC and SRAT.
  Xen-ia64 modify LSAPIC IDs of dom0, but it does not modify SRAT.
  So we decide disabling SRAT, SLIT of dom0 as first step of NUMA
  work.
