    ENGR00234722 USB: fix Kernel dump issue after USB driver loadable · 521a7f7a
    make shi authored
    - It is better to disable otgsc and wake up interrupt to avoid an
      abnormal interrupt happen during USB driver being removed.
    - If the USB host is already at low power mode, only need turn on
      the clock, no need turn off the clock.
    - Need discharge dp and dm during USB driver being removed ,in order
      to avoid a wakeup interrupt happen. And if the USB otg is in host
      mode, we should clear discharge dp and dm in fsl_otg_set_host()
      during system boot up.
