usb: move children to struct usb_port
The usb_device structure contains an array of usb_device "children".
This array is only valid if the usb_device is a hub, so it makes no
sense to store it there. Instead, store the usb_device child
in its parent usb_port structure.
Since usb_port is an internal USB core structure, add a new function to
get the USB device child, usb_hub_find_child(). Add a new macro,
usb_hub_get_each_child(), to iterate over all the children attached to a
particular USB hub.
Remove the printing the USB children array pointer from the usb-ip
driver, since it's really not necessary.
