When working in host mode, in certain conditions, when the USB
host controller is stressed, there is a HC died warning that comes up.
Fix this up by disabling SS instances in park mode for SC7280 and SC7180.

It is recommended to set this quirk for all Gen-1 SoCs. Will identify the
other SoCs and push a separate series for the same.

Changes in v2:
Updated commit text to include error message as well.
Minor other nits in commit text fixed.
