in short words (but manually typed, so time-consuming):
s/dt-bindings: regulator:/regulator: dt-bindings:/

Since I once have misunderstood that text block myself:
- this sounds like you are talking about the subject line as a whole
  and not only the prefix.

- Looking at common practice:
   git log  --pretty=format:%s  -- Documentation/devicetree/bindings/regulator/ | sed 's/^\([^:]*\):\([^:]*\):.*/\1:\2/'  | grep binding | head -n 100 | sort | uniq -c
   shows (besides random other stuff) around 70% "regulator: dt-bindings" and 30% "dt-bindings: regulator"
   so chances are that people might see a bunch of "dt-bindings: regulator" (happened to me once)
   if they do not invest time in doing proper statistic, I hove once thought: my prefix is right,
   so lets try to adjust the wording.

- for an unbiased reader, reading
  Documentation/devicetree/bindings/submitting-patches.rst helps

Maybe that helps to reduce some unnecessary churn in the future
