Why are these done as linear ranges when there's only one range? This
just adds overhead, just specify the one range directly in the desc and
use the appropriate ops.

Don't use of_regulator_match, just specify the DT names for the
regulator in the desc. Also it looks like you're trying to write a
switch statement with ifs here, just write a switch statement. It's
clearer and less error prone.
