irqchip: Remove asmlinkage from static functions

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]

  [ Modified for LSK from it's origin commit (see below) to only touch
    the irq-gic.c file so that we have a natural progression of the code
    before factoring out code bits into a library file for GICv3 support
    later - Christoffer ]

Drop asmlinkage here to avoid such warnings.
