While status is a relatively standard property, it's absence implies everything is OK. There no need for it here as-is.
Additionally, the canonical value is "okay", not "enabled", so this would fail were we to use of_device_is_available in the idle states parsing.

Do we expect that some idle states won't be available on some boards built from the same platform?
Mark.
