irqchip/ath79-misc: Fix missing prototypes warnings

ath79_misc_irq_init() was defined but unused since commit 51fa4f8912c0
("MIPS: ath79: drop legacy IRQ code"), so it's time to drop it.

The build also warns about a missing prototype of get_c0_perfcount_int().

Remove the stale leftover function and add the missing include.
