bus: mhi: ep: Use bus callbacks for .probe() and .remove()
These are nearly identical to the driver callbacks, the only relevant
difference is that the bus remove method returns void (instead of an int
where the value is ignored).
The objective is to get rid of users of struct device_driver callbacks
.probe(), and .remove() to eventually remove these.
