regulator: s5m8767: Use DIV_ROUND_UP to calculate selector

Browse source

Integer division may truncate the result.
Use DIV_ROUND_UP to ensure new voltage setting falls within specified range.

Also properly handle the case min_vol < desc->min to ensure we don't return
negative value for selector.
