Default ENGR00121385 MX51: Leave MC13892 VUSB Turned on for USB OTG to work

From: Dinh Nguyen <r00091@freescale.com>

Short-term solution is to leave VUSB always on for USB OTG port
to work. Long-term solution would be for USB driver to enable the
necessary regulators. That will be addressed by a different CR.
