x86: apic: simplify secondary CPU wakeup methods

Browse Source 
Impact: cleanup

- rename apic->wakeup_cpu  to apic->wakeup_secondary_cpu, to
  make it apparent that this is an SMP-only method

- handle NULL ->wakeup_secondary_cpus to mean the default INIT
  wakeup sequence - this allows simplification of the APIC
  driver templates.
