reset: Add reset controller API This adds a simple API for devices to request being reset by separate reset controller hardware and implements the reset signal device tree binding.

reset: Add of_reset_control_get In some cases, you might need to deassert from reset an hardware block that doesn't associated to a struct device (CPUs, timers, etc.). Add a small helper to retrieve the reset controller from the device tree without the need to pass a struct device.
