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.
