If the cpu-idle-states is missing from the DT in the first place, do not fail on removing in. Just move on and do not even print an error, since not being able to remove something which is not there in the first place is not an error and surely does not justify failing to boot.
Turn the surrounding prints into debugs to reduce the useless noise.
