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.
