Using the augmented reset driver for the Versatile family, we can move the reset handling for the Integrator out of the machine. We add a "syscon" attribute to the core module, and access the syscon registers using this handle. We need to select SYSCON, POWER, POWER_RESET and POWER_RESET_VERSATILE in order for the restart functionality to always be available on all systems (it should not be optional).
