Add a driver to provide DVS for the Simtec Osiris module to reduce the power consumption whilst idling. The DVS driver alters the voltage supplied to the ARM core depending on the frequency it is running at. The driver itself does not do any of the frequency alteration, which is left up to the cpufreq driver.
