Tejun Heo 299a180aec x86-32, NUMA: Update numaq to use new NUMA init protocol 
Update numaq such that it calls numa_add_memblk() and sets
numa_nodes_parsed instead of directly diddling with NUMA states.  The
original get_memcfg_numaq() is renamed to numaq_numa_init() and new
get_memcfg_numaq() is created in numa_32.c.

The shim numa_add_memblk() implementation handles node_start/end_pfn[]
and node_set_online() for nodes with memory.  The new
get_memcfg_numaq() exactly the same with get_memcfg_from_srat() other
than calling the numaq init function.  Things get_memcfgs_numaq() do
are not strictly necessary for numaq but added for consistency and to
help unifying NUMA init handling.
