powerpc/mm: Always update max/min_low_pfn in mem_topology_setup()
For both CONFIG_NUMA enabled/disabled use mem_topology_setup() to
update max/min_low_pfn.
This also adds min_low_pfn update to CONFIG_NUMA which was initialized
to zero before. (mpe: Though MEMORY_START is == 0 for PPC64=y which is
all possible NUMA=y systems)
