[Qemu-arm] [RFC v4 03/16] hw/boards: Add a MachineState parameter to kvm_type callback

[Eric Auger]

On ARM, the kvm_type will be resolved by querying the KVMState.
Let's add the MachineState handle to the callback so that we
can retrieve the  KVMState handle. in kvm_init, when the callback
is called, the kvm_state variable is not yet set.
