Changelog v1->v2:
- This patch has been splitted out of my previous imx25/35/51 USB patchset.
  It's made from the "ARM: dts: i.MX51: Add a second usbphy." and the
  "ARM: dts: mbimxsd51 baseboard: Add USB host support" patchset.
  - USB OTG support was added.
  - The second USB phy was moved outside of imx51.dtsi
  - "phy_type = "ulpi";" was added to the usbh1 node, like with the imx51 babbage.
  - Now depends on the "chipidea: usbmisc_imx: Allow USB OTG to work on mx51" patch
    which is queued by Peter Chen.
