This is just regulator_enable_regmap() isn't it? Same for disable,
unless I'm missing something (which is possible).

This isn't *quite* regulator_is_enabled_regmap() as it explicitly checks
if the disable value is set and errors otherwise which would be a good
fix for that. Could you do a patch for that?
