commit af65d1ad416bc6e069ccb9e649faeda224248f96 upstream.
Backport summary: for 5.4 kernel ICX PCIe Gen4 support.
Previously we did not save and restore the AER configuration on
suspend/resume, so the configuration may be lost after resume.
Save the AER configuration during suspend and restore it during resume.
