regulator: mt6359: Remove shift fields from struct mt6359_regulator_info
The shift setting can be calculated via the corresponding mask field, so remove these shift fields. Signed-off-by: Axel Lin <axel.lin@ingics.com> Link: https://lore.kernel.org/r/20210629130503.2183574-2-axel.lin@ingics.com Signed-off-by: Mark Brown <broonie@kernel.org>
