The following patch does not apply to upstream any more and needs some
more work to make it work fully again. I am not sure if we are still
able to set the UART to a none standard baud rate.

Subject: [PATCH] MLK-22099 usb: host: xhci: do warm reset for link state
rxdect
As some USB3 port will lose link state while system sleep, then
the link state will be at rxdect after resume, we need a warm
reset to bring it back, so add the rxdect condition for CAS
missing.
