[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[].
