ARM: shmobile: remove use of gic_arch_extn.irq_set_wake

Browse Source 
shmobile only uses gic_arch_extn.irq_set_wake to prevent the GIC
from returning -ENXIO when receiving a wake-up configuration request.

It is a lot simpler to tell the irq layer that we don't need any
configuration by using the IRQCHIP_SKIP_SET_WAKE, thanks to the
new gic_set_irqchip_flags function.
