ACPI: Store SRAT table revision
In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides 32bits for these. The new fields were reserved before. According to the ACPI spec, the OS must disregrard reserved fields. In order to know whether or not, we must know what version the SRAT table has. This patch stores the SRAT table revision for later consumption by arch specific __init functions.
