[PATCHv2] irqchip: ath79: remove unused function

[Rosen Penev]

ath79_cpu_irq_init() was part of legacy pre-OF code that got removed a
while back. Remove it to get rid of a missing prototype error that the
kernel test robot also found but was never fixed.

Reported-by: kernel test robot <lkp@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-kbuild-all/202412011509.kGQkDr1y-lkp@xxxxxxxxx/
Fixes: 51fa4f8912c0 ("MIPS: ath79: drop legacy IRQ code")
