[PATCH 1/7] powerpc/numa: Remove redundant coregroup enablement

[Srikar Dronamraju <srikar@linux.ibm.com>]

parse_numa_properties() determines whether the coregroup associativity
level is present and sets coregroup_enabled before find_possible_nodes()
is called.

Therefore, there is no need for find_possible_nodes() to determine the
same information again from the length of the associativity domain
property.
