xen: PV on HVM: support PV spinlocks and IPIs

Initialize PV spinlocks on boot CPU right after native_smp_prepare_cpus
(that switch to APIC mode and initialize APIC routing); on secondary
CPUs on CPU_UP_PREPARE.

Enable the usage of event channels to send and receive IPIs when
running as a PV on HVM guest.
