acpi: Validate processor id when mapping the processor
When we want to identify whether the proc_id is unreasonable or not, we
can call the "acpi_processor_validate_proc_id" function. It will search
in the duplicate IDs. If we find the proc_id in the IDs, we return true
to the call function. Conversely, the false represents available.
When we establish all possible cpuid <-> nodeid mapping to handle the
cpu hotplugs, we will use the proc_id from ACPI table.
We do validation when we get the proc_id. If the result is true, we
will stop the mapping.
