Subject: [PATCH 2/2] irqchip: gic: remove reduntant gic_set_irqchip_flags

Now that the GIC chip implementation enables IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND by default, the platforms requiring them need
not override the irqchip flags as before.

This patch removes all the users of gic_set_irqchip_flags and the
function itself.
