drivers: usb: dwc3: Add XMIT_DEV command

Starting with synopsis version 220A the command to wake up the
host changed from 0x3 to 0x7. The code is fixed accordingly.
The problem that was seen is that upon MBIM function
suspend, a remote wakeup from the IPA side wouldn't
wake up the host, and at some point a stall in the IPA would be
seen.
