The tcpc_dev structure lists a number of callbacks as required when
implementing a TCPM driver. tcpc_dev->init() is not listed as required.
Currently tcpc_dev->init() is called irrespective of whether or not the
callback is set. Let's conditionally call init() as with other non-required
callbacks such as get_current_limit() or set_current_limit().
