imx233: fix regulator voltage setting + always enable DCDC mode
Make sure DCDC is running at boot (it is disabled by default when
5V is present and we don't want to rely on the bootloader to
change this).
When changing the voltage on a regulator, it usually takes 2ms for
the voltage to stabilize. In DCDC mode, there is an irq to notify
about the event so use it ! This is especially important when
changing cpu frequency because increasing the cpu freq while the
voltage is rising is unreliable.
