ENGR00234722 USB: fix Kernel dump issue after USB driver loadable
- 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.
