    USB: add reset endpoint operations

    Wireless USB endpoint state has a sequence number and a current
    window and not just a single toggle bit.  So allow HCDs to provide a
    endpoint_reset method and call this or clear the software toggles as
    required (after a clear halt, set configuration etc.).

    usb_settoggle() and friends are then HCD internal and are moved into
    core/hcd.h and all device drivers call usb_reset_endpoint() instead.

    If the device endpoint state has been reset (with a clear halt) but
    the host endpoint state has not then subsequent data transfers will
    not complete. The device will only work again after it is reset or
    disconnected.
