This commit is based on previous work by Robert Baldyga which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.

The USB PHY member of the OTG structure is renamed to 'usb_phy' and modifications are done in all drivers accessing it. Renaming this pointer will allow to keep the compatibility for USB PHY drivers.
