This is not a very good analogy because both relationships need to be
The practical consideration is the lifetime of the target device.
If the target device should/must have a lifetime (as viewed from the host)
outside that of the uart, then the target device should not be a slave device.
Object lifetime is controlled by expressions of ownership or scope.
Since devicetree offers no expression of ownership, scope is the
obvious and natural way to control lifetime.
