usb: Replace device_destroy bus op with a child_detach port op
Note this fixes 2 things in one go, first of all the device_destroy bus op should be a device_detach bus op, as pending async packets from the device should be cancelled on detach not on destroy. Secondly having this as a bus op won't work with companion controllers, since then there will be 1 bus driven by the ehci controller and thus 1 set of bus ops, but the device being detached may be downstream of a handed over port. Making the detach of a downstream device a port op allows the ehci controller to forward this to the companion controller port for handed over ports.
