6 years agousb: hub: identify the hub-device to usb_hub_reset_devices

usb: hub: identify the hub-device to usb_hub_reset_devices

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.

Previously, the usb_hub.c code did not include such context and
always started resets from port number 1, performing multiple
reset-requests for the same devices:

       /*
        * Reset any devices that may be in a bad state when applying
        * the power.  This is a __weak function.  Resetting of the devices
        * should occur in the board file of the device.
        */
       for (i = 0; i < dev->maxchild; i++)
              usb_hub_reset_devices(i + 1);

This adds an additional 'hub' parameter to usb_hub_reset_devices
that provides the context to fully qualify the port-number in.

Existing implementations are changed to accept and ignore the new
parameter.
