irqchip: atmel-aic: Fix irqdomain initialization 

First of all IRQCHIP_SKIP_SET_WAKE is not a valid irq_gc_flags and thus
should not be passed as the last argument of
irq_alloc_domain_generic_chips.

Then pass the correct handler (handle_fasteoi_irq) to
irq_alloc_domain_generic_chips instead of manually re-setting it in the
initialization loop.

And eventually initialize default irq flags to the pseudo standard:
IRQ_REQUEST | IRQ_PROBE | IRQ_AUTOEN.
