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.
