USB: OTG: msm: Implement data contact detection based on timeout

Data contact can be detected by either current source or timeout
methods.  The current source method is not working for an unknown
reason.  Implement timeout based data contact detection.  The spec
allows any timeout between 300msec to 900msec.  Use 600msec.
