parisc: Fix CPU hotplug rendenzvous code
Fix the PDC rendenzvous code to clear all pending external intrrupts
before entering the waiting loop.
Without clearing them before, the CPU was waken up immediately again.
This fixes the CPU hotplug on Linux, which can be run with
chcpu -d 2 # to disable CPU2
chcpu -e 2 # to wake up CPU2
