GIC state is saved on system suspend by calling gic_suspend
(this function does not change current state of the GIC but only
saves the values of configuration registers).
The state of GIC has to be restored by calling gic_resume, but only
if the gic_suspend has succeeded. If gic_suspend fails, we'll just
restore interrupts configuration and abort suspend.

This should be part of the previous patch.
