    arm64: dts: qcom: ipq8074: Disable SS instance in Parkmode for USB
    
    [ Upstream commit dc6ba95c6c4400a84cca5b419b34ae852a08cfb5 ]
    
    For Gen-1 targets like IPQ8074, 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 IPQ8074 to mitigate this issue.
