ANDROID: gic-v3: Export gic_v3_resume() for vendor GIC enhancements

Browse source 
syscore ops in gic-v3 takes care of invoking gic_v3_resume() when
exiting from "deep" suspend. However for "s2idle" suspend syscore
ops will not get invoked.

Vendor modules can register for s2idle notifications and
invoke gic_v3_resume() when the first cpu is waking up from s2idle.
