Summary

Some devices (e.g. ASM1074) reports remote wakeup working, but the
functionality is not implemented on the controller. As a result,
they spam dmesg with {resume,suspend}_peer error message.

97–98	It's my first time to usb code, and I'm not sure how to implement this using existing `remote_wakeup` as `usb_dev_{resume,suspend}_peer()` don't seem to use it.

97–98	It's my first time to usb code, and I'm not sure how to implement this using existing `remote_wakeup` as `usb_dev_{resume,suspend}_peer()` don't seem to use it. I think we can test the quirk in tr_handle_clear_wakeup branch of usb_handle_request to skip calling usb_handle_remote_wakeup.
