dm: usb: Rename usb_find_child to usb_find_emul_child
Now that we unbind usb devices from usb_stop() usb_find_child() is only necessary to deal with emulated usb devices. Rename it to make this clear and add a #ifdef to make it a nop in other cases. Note the #ifdef turns usb_find_emul_child() into a nop, rather then not building it and adding another #ifdef to the caller, this is done this way because adding a #ifdef to the caller is somewhat hairy.
