usb: misc: Add USB super speed re-driver support



Add redriver support for improving signal quality on some board
designs.

Different board level designs may need to use different parameters,
so expose four interfaces under /sys/kerne/debug for the
tuning, that is eq, flat_gain, output_comp and loss_match.
