Some of the new field added to socinfo structure with version 21, 22 and 23 which is only used by boot firmware and it is of no use for Linux.Add reserve field in socinfo so that the structure remain updated and prepared if we get any new field in future which could be used by Linux. While at it, also updates switch case for backward compatibility if the SoC runs with boot firmware which has these new version added.
