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.
