[RFC PATCH 8/8] spapr: move memory/cpu less check to spapr_numa_FORM1_affinity_init()

[Daniel Henrique Barboza <danielhb413@gmail.com>]

FORM2 NUMA affinity is prepared to deal with memory/cpu less
NUMA nodes. This is used by the DAX KMEM driver to locate a
PAPR SCM device that has a different latency than the original
NUMA node from the regular memory.

Move this verification to FORM1 affinity code.
