[PATCH 13/14] x86, mm: Parse numa info early

[Yinghai Lu <yinghai@kernel.org>]

Parse numa info at first and store info into numa_meminfo.

call early_initmem_init before init_memory_mapping(), will
have numa info ready at first, and will still keep numaq, acpi_numa,
amd_numa, dummy fall back sequence.

SLIT and numa emulation handling are still left in initmem_init().
