kvm: Add a new machine option kvm-type

Browse source 
Targets like ppc64 support different types of KVM, one which use
hypervisor mode and the other which doesn't. Add a new machine
option kvm-type that helps in selecting the respective ones
We also add a new QEMUMachine callback get_vm_type that helps
in mapping the string representation of kvm type specified.
