Subject: [VOYAGER] add prefill_possible_mask() to fix linker breakage

    x86: move prefill_possible_map calling early

prefill_possible_mask() was hidden under CONFIG_HOTPLUG_CPU rendering
it invisitble to voyager.  Since this commit it's exposed, but not
provided by the voyager subarch, so add a dummy stub to fix the link
breakage.
