[IA64] Increase max node count on SN platforms
Add support in IA64 acpi for platforms that support more than 256 nodes. Currently, ACPI is limited to 256 nodes because the proximity domain number is 8-bits. Long term, we expect to use ACPI3.0 to support >256 nodes. This patch is an interim solution that works with platforms that pass the high order bits of the proximity domain in "reserved" fields of the ACPI tables. This code is enabled ONLY on SN platforms.
