[PATCHv6 19/19] usb: otg: Convert all users to pass struct usb_otg for OTG functions

From: Heikki Krogerus
Date: Fri Oct 28 2011 - 08:36:17 EST

This changes the otg functions so that they receive struct
otg instead of struct usb_phy as parameter and
converts all users of these functions to pass the otg member
of their usb_phy.

Includes fixes to IMX code from Sascha Hauer.
