There's no build time dependency here, please also add an || COMPILE_TEST to
help with build coverage.

This looks like it's reading back a status bit from the hardware not the
state requested by software - I'd expect an _is_enabled() to reference
the same bit that's updated by the enable/disable functions. This looks
like a better fit for _get_status().

You don't need to open code the matching any more, just set of_match and
regulators_node in the regulator_desc and the core will do it for you.
