Again, this should be part of the regulator API code not hidden away
where it will only get reviewed by device tree people.

This seems at best confusing - the fixed voltage regulator is a
particular regulator driver, and the general concept of a fixed voltage
regulator is still a subset of regulators.

Much of this is specific to the Linux fixed voltage regulator driver
rather than a generic regulator with a fixed voltage.
