[PATCH v5 05/28] bus: simple-pm-bus: Remove child devices when the bus is unbound

[Herve Codina]

During its probe, the simple-pm-bus driver (simple-pm-bus compatible
variant) populates its child devices but it doesn't touch them during
its removal.

This leads to bus child devices present and bound to drivers whereas the
bus itself is unbound.

Be consistent and remove child devices when the bus itself is unbound.
