Add CPU_METHOD_OF_DECLARE to use enable_method property of cpus node. To keep compatibility with older DTBs lets keep older method of registering smp_ops via machine_descriptor.

Are you sure that smp_ops from DT will be set after mdesc->smp? The arm_dt_init_cpu_maps() is called before smp_set_ops(mdesc->smp)... Have you actually tried this? Best regards, Krzysztof
