Following the previous patches, which introduced various changes in pvscsi's pci configuration space (device subsystem id and revision, msi offset), this patch introduces a boolean property 'x-old-pci-configuration' to pvscsi. Its default value is false, exposing the above changes in the pci config space. Setting 'x-old-pci-configuration' to 'on' preserves the old behavior, which allows migration to older versions.
