ARM: OMAP: USB: register hwmods of usbhs

The hwmod structure of usb_host_hs  and usb_tll are
retrieved and registered with omap device

Reviewed-by: Partha Basak <parthab@india.ti.com>
[paul@pwsan.com: this patch is merged with the understanding that the
 authors will send patches for the next merge window to remove the
 multiple hwmods-per-omap_device]
