rust: platform: require Send for Driver trait implementers
The instance of Self, returned and created by Driver::probe() is
dropped in the bus' remove() callback.
Request implementers of the Driver trait to implement Send, since the
remove() callback is not guaranteed to run from the same thread as
probe().
