parisc: convert to asm-generic/hardirq.h

/* hardirq.h: PA-RISC hard IRQ support.

 *

 * Copyright (C) 2001 Matthew Wilcox <matthew@wil.cx>

 *

 * The locking is really quite interesting.  There's a cpu-local

 * count of how many interrupts are being handled, and a global

 * lock.  An interrupt can only be serviced if the global lock

 * is free.  You can't be sure no more interrupts are being

 * serviced until you've acquired the lock and then checked

 * all the per-cpu interrupt counts are all zero.  It's a specialised

 * br_lock, and that's exactly how Sparc does it.  We don't because

 * it's more locking for us.  This way is lock-free in the interrupt path.
