[PATCH] ARM: dts: imx53: Add USB support for M53EVK

[Marek Vasut]

Add USB support for M53EVK. The configuration is such that USB Host1
port is used as Host and the USB OTG port is used as Peripheral thus
far. Once OTG is properly fixed, the OTG will be further adjusted.

To maintain the alphabetical order, 'usbh1' should be put before
'usbotg'.  I just fixed it up and applied the patch.

Ah, you're right. Thank you and sorry for adding more burden unto you.
