Sama5d2 SoC has a completely new shutdown controller with new features and register layout. It thus makes sense to add a new driver for this new peripheral. This driver is Device Tree only and handles events from the wake-up pin and the RTC. As the register layout may change in the future, so some values are encoded in a configuration structure.
