HVMlite secondary VCPUs use baremetal bringup path (i.e. native_*

If we always provided an emulated APIC could we use the native SMP
bring-up instead?

We do use native SMP bringup now (wrapped in xen_hvm_cpu_up/xen_cpu_die/xen_play_dead)), I added a couple of PV APIC ops to help with that, most notably xen_wakeup_secondary_cpu().
