6.1-stable review patch. If anyone has any objections, please let me know.

From: Krishna Kurapati <quic_kriskura@xxxxxxxxxxx>
[ 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.
