x86-64, NUMA: Use common {cpu|mem}_nodes_parsed
ACPI and amd are using separate nodes_parsed masks. Add
{cpu|mem}_nodes_parsed and use them in all NUMA init methods.
Initialization of the masks and building node_possible_map are now
handled commonly by initmem_init().
dummy_numa_init() is updated to set node 0 on both masks. While at
it, move the info messages from scan to init.
