[SPARC64]: Send all device interrupts via one PIL.
This is the first in a series of cleanups that will hopefully allow a seamless attempt at using the generic IRQ handling infrastructure in the Linux kernel. Define PIL_DEVICE_IRQ and vector all device interrupts through there. Get rid of the ugly pil0_dummy_{bucket,desc}, instead vector the timer interrupt directly to a specific handler since the timer interrupt is the only event that will be signaled on PIL 14. The irq_worklist is now in the per-cpu trap_block[]. Signed-off-by: David S. Miller <davem@davemloft.net>

/* To avoid some locking problems, we hard allocate certain PILs
