On the mx53loco board with mc34708 PMIC it is necessary to turn on VUSB regulator
so that the mx53 USBH1 PHY receives the 3.3V voltage.
Tested by inserting a USB pen drive in the upper USB slot (USBH1) and then issued the
commands:
usb start
usb info
,which correctly detected and printed the USB pen drive information.
