    usb ehci - Fix machine freezes from shutdown race
    EHCI's shutdown code was killing the chipset without first killing the
    interrupt, and it was also handing EHCI back to the BIOS without first
    waiting for the shutdown reset to complete.  Either can lock the machine
    up on shutdown/reboot.
