arm64: dts: qcom: sm6350: Disable SS instance in Parkmode for USB

commit c5d57eb7d06df16c07037cea5dacfd74d49d1833 upstream.

For Gen-1 targets like SM6350, it is seen that stressing out the
controller in host mode results in HC died error:

 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

And at this instant only restarting the host mode fixes it. Disable
SuperSpeed instance in park mode for SM6350 to mitigate this issue.
