[SPARC64]: Kill ino_bucket->pil
And reuse that struct member for virt_irq, which will be used in future changesets for the implementation of mapping between real and virtual IRQ numbers. This nicely kills off a ton of SBUS and PCI controller PIL assignment code which is no longer necessary. Signed-off-by: David S. Miller <davem@davemloft.net>
