(change CI13XXX to CI13 to avoid junk email check)
Now, we have handled vbus session in core driver when the
vbus interrupt occurs, so our pullup operations are all
according to vbus.
Of cource, the software can still call .pullup when device connects
to host if it wants to connect/disconnect with host.
