In order to rely on the CPU PM implementation for saving and restoring
of CPU subsystems like GIC and PMU, the arch Kconfig must be augmented
to select the CONFIG_CPU_PM option when SUSPEND or CPU_IDLE kernel
implementation are selected. This patch adds the appropriate selection
entry in the arm64 Kconfig file.
