The IRQ_PER_CPU Kconfig symbol was removed in the following commit:
Commit 6a58fb3bad099076f36f0f30f44507bc3275cdb6 ("genirq: Remove
CONFIG_IRQ_PER_CPU") merged in v2.6.39-rc1.
But IRQ_PER_CPU wasn't removed from any of the architecture Kconfig
files where it was defined or selected. It's completely unused so remove
the remaining references.

Based on v3.7-rc5.
Compile tested defconfigs for bfin, ia64, mips, parisc, powerpc, sh, but
not hexagon.
Grepped entire tree to check no references to CONFIG_IRQ_PER_CPU, and
grepped arch/ for Kconfig files referencing IRQ_PER_CPU.
