regulator: rk808: Perform trivial code cleanups

Perform a few trivial code cleanups, to improve the accuracy and wording of
a couple of comments and the module description, and to avoid line wrapping
in a few places by using the 100-column width a bit better.

No intended functional changes are introduced by these code cleanups.
