ANDROID: gic-v3: Change GIC v3 vendor hook to restricted

Some of the irq migration paths call chip set affinity, after
current CPU is marked offline in cpu_online_mask. These
chip set affinity calls do not invoke vendor trace hooks.
So, convert gic_v3_set_affinity() vendor hook to a restricted
hook, to allow trace hook to be called from these irq migration
paths.
