arm64: dts: qcom: msm8998: Disable SS instance in Parkmode for USB
[ Upstream commit 0046325ae52079b46da13a7f84dd7b2a6f7c38f8 ]
For Gen-1 targets like MSM8998, 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 MSM8998 to mitigate this issue.
