    Apply hw workaround required for all SB600 revisions and SB700 revisions
    A12 and A13 to avoid USB subsystem hang symptom. The USB subsystem hang
    symptom is observed when the system has multiple USB devices connected to it
    or one USB device is often re-connected. In some cases a USB hub may be
    required to observe this symptom.

    This patch works around the problem by correcting the internal register setting
    that will help by changing the behavior of the internal logic to avoid the
    USB subsystem hang issue. The change in the behavior of the logic does not
    impact the normal operation of the USB subsystem.

    This fix has been discussed, developped, reviewed, polished up
    and tested on current-users by several people. Thread starts at:
