iicbus: Use device_delete_children() instead of explicit child removal
If the bus is detached and deleted by a call to device_delete_child() or
device_delete_children() on a device higher in the tree, I²C children
were already detached and deleted. So the device_t pointer stored in sc
points to freed memory: we must not try to delete it again.
By using device_delete_children(), we let subr_bus.c figure out if there
are children to take care of.
While here, make sure iicbus_detach() and iicoc_detach() call
device_delete_children() too, to be safe.
