usb: otg: Convert all users to pass struct usb_otg for OTG functions

Browse Source 
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.
