[PATCH] ARM: ux500: implement set_wake() callback for the GIC

[Linus Walleij]

From: Linus Walleij <linus.walleij at linaro.org>

The Ux500 will be able to wake up on any IRQ, so implement a
.set_wake() callback that just returns 0 instead of the default
in common/gic.c which returns an error if you try to set
wakeup on the GIC.
