Support "GenerationInUse" PCIe device property

This commit adds support for PCIe device property "GenerationInUse",
and let management APIs like redfish can expose the information.

New property:
GenerationInUse   : The PCIe interface generation in use by the device.

Tested:
Ensure DBus is created and the value is correct of new property.

Dbus Sample output:
