We currently use the SMBIOS type 1 'family' string to identify Ampere machines that require a EFI workaround, but this is not broad enough, as OEMs often put arbitrary names in that field (such as 'Server') So instead, let's use the SMBIOS type 4 records that describe the actual CPU rather than the system.
