For targets that have only USB3 Gen-1 DWC3 controllers, it is recommended
to disable SS instance in park mode to avoid HC died error when working
in host mode in situations where the controller is stressed out:

 xhci-hcd.12.auto: xHCI host not responding to stop endpoint command
 xhci-hcd.12.auto: xHCI host controller not responding, assume dead
 xhci-hcd.12.auto: HC died; cleaning up

Note that in case some SoC's have missed this change, I will send a
follow up series to fix them up.
