ENGR00137317-2 USB: handle non-intent wakeup irq triggered by PHCD change
PORTSC PHCD will be changed while system shuts down usb host. This triggers
wake-up interrupt. But it's not host wake-up or device wake-up. OWIR bit in
USBCTRL doesn't be cleared. It keeps bring interrupt on. So
- Clear OWIR bit in wakeup ISR if host/device doesn't need to wake up.
- Close wakeup irq before shut down USB host.
