ARM: gic: Use cpu pm notifiers to save gic state
When the cpu is powered down in a low power mode, the gic cpu
interface may be reset, and when the cpu cluster is powered
down, the gic distributor may also be reset.
This patch uses CPU_PM_ENTER and CPU_PM_EXIT notifiers to save
and restore the gic cpu interface registers, and the
CPU_CLUSTER_PM_ENTER and CPU_CLUSTER_PM_EXIT notifiers to save
and restore the gic distributor registers.
Merge note:
Samsung had already applied the changes to struct gic_chip_data, although it
still remains in the .c file instead of having been moved to the header.
