numa: move default mapping init to machine

there is no need use cpu_index_to_instance_props() for setting
default cpu -> node mapping. Generic machine code can do it
without cpu_index by just enabling already preset defaults
in possible_cpus.

PS:
as bonus it makes one less user of cpu_index_to_instance_props()
