Subject: irqchip/mxs: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND
From: Stefan Wahren <stefan.wahren@xxxxxxxx>
[ Upstream commit 88e20c74ee020f9e0c99dfce0dd9aa61c3f0cca0 ]
The ICOLL controller doesn't provide any facility to configure the
wakeup sources. That's the reason why this implementation lacks
the irq_set_wake implementation. But this prevent us from properly
entering power management states like "suspend to idle".
So enable the flags IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND to let the irqchip core allows and handles
the power management.
