MLK-12247 usb: chipidea: udc: disconnect host if system enters suspend It is better we disconnect (pulldown dp) host when the system enters suspend if the host did not suspend bus beforehand, it can avoid unnecessary udc suspend irq during usb enters suspend. This unexpected suspend irq occurs due to the udc still pulls up dp, but the host suspends bus due to it finds the device has disconnected. The device turns off high speed terminal will be considered a disconnection event from the host. It also fixes the bug ENGR00325724 describes.
