haven: add stubs to haven client exposed APIs 



There are Non-VM (Virtual Machine) supported target drivers which
may refer some of the APIs defined for VMs. But those drivers are
compiled irrespective of VM or non-VM configurations. Add stubs to
support to compile drivers for non vm supported targets.
