irqchip: Remove asmlinkage from static functions

LTO patches add __visible to the asmlinkage define, causing
compilation warnings like:

  drivers/irqchip/irq-gic.c:283:1: warning: 'externally_visible'
  attribute have effect only on public objects [-Wattributes]

Drop asmlinkage here to avoid such warnings.
