[ARM] Provide a method to alter the control register
i.MX needs to tweak the control register to support CPU frequency scaling. Rather than have folk blindly try and change the control register by writing to it and then wondering why it doesn't work, provide a method (which is safe for UP only, and therefore only available for UP) to achieve this.
