[PATCH 13/37] xen/x86: decouple processor_nodes_parsed from acpi numa functions

[Wei Chen <wei.chen@xxxxxxx>]

Xen is using processor_nodes_parsed to record parsed processor nodes
from ACPI table or other firmware provided resource table. This
variable is used in ACPI numa functions directly. In follow-up
patchs, neutral NUMA code will be abstracted and move to other files.
So in this patch, we introduce numa_set_processor_nodes_parsed helper
to decouple processor_nodes_parsed from acpi numa functions.
