spapr: Add cpu_apply hook to capabilities

Browse source 
spapr capabilities have an apply hook to actually activate (or deactivate)
the feature in the system at reset time.  However, a number of capabilities
affect the setup of cpus, and need to be applied to each of them -
including hotplugged cpus for extra complication.  To make this simpler,
add an optional cpu_apply hook that is called from spapr_cpu_reset().
