[U-Boot] [PATCH v2 1/3] usb: hub: identify the hub-device to usb_hub_reset_devices

[Philipp Tomsich]

When usb_hub_reset_devices is called, it should be passed both an
indicator which hub it should operate on and what port number (local
to that hub) should be reset.

This adds an additional 'hub' parameter to usb_hub_reset_devices.
Existing implementations are changed to simply ignore the new
parameter.
