parisc: Add PDC locking functions for rendezvous code
Add pdc_cpu_rendezvous_lock() and pdc_cpu_rendezvous_unlock()
to lock PDC while CPU is transitioning into rendezvous state.
This is needed, because the transition phase may take up to 8 seconds.
Add pdc_pat_get_PDC_entrypoint() to get PDC entry point for current CPU.
