spapr: add uuid/host details to device tree
Useful for identifying the guest/host uniquely within the guest. Adding following properties to the guest root node. vm,uuid - uuid of the guest host-model - Host model number host-serial - Host machine serial number hypervisor type - Tells its "kvm" Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
