Subject: [PATCH 3.17 104/122] irqchip: atmel-aic: Fix irqdomain initialization

3.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris Brezillon <boris.brezillon@...e-electrons.com>

commit 45977fe35bf014f5cf9552717e1320783398ae0d upstream.

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.
