libpayload: usb: Remove generic roothub reset port function

The generic roothub reset port function is overly broad and does some
    things which may be undesirable, such as issuing multiple resets to a
    port if the reset is deemed to have finished too quickly. Remove the
    generic function and replace it with a controller-specific function,
    currently only implemented for xhci.
