greybus: Use bus methods for .probe() and .remove()

These are nearly identical to the respective driver callbacks. The only
difference is that .remove() returns void instead of int.

The objective is to get rid of users of struct device_driver callbacks
.probe() and .remove() to eventually remove these.
