ARM64: dts: rk3399: prevent out of bounds accesses to array

It will return state++ when get the idle state, so we need fill
anothor idle power(=WFI) in the parameter of EAS, code as below:

static int group_idle_state(struct sched_group *sg)
{
        int i, state = INT_MAX;

        /* Find the shallowest idle state in the sched group. */
        for_each_cpu(i, sched_group_cpus(sg))
                state = min(state, idle_get_state_idx(cpu_rq(i)));

        /* Take non-cpuidle idling into account (active idle/arch_cpu_idle()) */
        state++;

        return state;
}
