[PATCH] i383 numa: fix numaq/summit apicid conflict
This allows numaq to properly align cpus to their given node during
boot. Pass logical apicid to apicid_to_node and allow the summit
sub-arch to use physical apicid (hard_smp_processor_id()).
Tested against numaq and summit based systems with no issues.
