SoB ordering seems wrong.

so unlike in the sdm845 case where we map these levels to
(contiguous) corners before passing it over to rpm, we seem
to pass these as-is to rpm, right?
Does this work if the user passes some value which does not
really map to a level defined here?
For instance if value passed is 17 for instance do we fall back to
16?
