[SPARC]: Kill __irq_itoa().

This ugly hack was long overdue to die.

It was a way to print out Sparc interrupts in a more freindly format,
since IRQ numbers were arbitrary opaque 32-bit integers which vectored
into PIL levels.  These 32-bit integers were not necessarily in the
0-->NR_IRQS range, but the PILs they vectored to were.

The idea now is that we will increase NR_IRQS a little bit and use a
virtual<-->real IRQ number mapping scheme similar to PowerPC.

That makes this IRQ printing hack irrelevant, and furthermore only a
handful of drivers actually used __irq_itoa() making it even less
useful.
