arm64: kernel: add PM build infrastructure
This patch adds the required makefile and kconfig entries to enable PM for arm64 systems. The kernel relies on the cpu_{suspend}/{resume} infrastructure to properly save the context for a CPU and put it to sleep, hence this patch adds the config option required to enable cpu_{suspend}/{resume} API. 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 also augmented to select the CONFIG_CPU_PM option when SUSPEND or CPU_IDLE kernel implementations are selected.
