mx31moboard: add support for usb OTG device (v3)
This is used on all board of our system, so again this is done in the
mx31moboard.c file.
changes since v2: call to gpio_request added in platform code, and
moved device initialization in baseboard files.
changes since v1: pins are claimed in another patch
