hw/boards: Add a MachineState parameter to kvm_type callback
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.
