Re: [RFC FIX v1 1/2] powerpc: Discover radix availability before scanning the memory nodes

Currently device tree nodes for memory are scanned before the
radix feature is discovered in mmu_early_init_devtree(). Move this
routine ahead of scanning memory nodes so that we know if the
guest is radix or not when scanning ibm,dynamic-reconfiguration-memory.
