usb: assert on calling usb_attach(port, NULL) on a port without a dev
with the "usb-ehci: cleanup port reset handling" patch in place no callers
are calling usb_attach(port, NULL) for a port where port->dev is NULL.
Doing that makes no sense as that causes the port detach op to get called
for a port with nothing attached. Add an assert that port->dev != NULL when
dev == NULL, and remove the check for not having a port->dev in the dev == NULL
case.

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.
