LoongArch: Add all CPUs enabled by fdt to NUMA node 0

Browse source

commit 3de9c42d02 upstream.

NUMA enabled kernel on FDT based machine fails to boot because CPUs
are all in NUMA_NO_NODE and mm subsystem won't accept that.

Fix by adding them to default NUMA node at FDT parsing phase and move
numa_add_cpu(0) to a later point.
