regulator: s2mps11: Don't check enable_shift before setting enable ramp rate
Current code misses updating the register when enable_shift is 0. e.g. S2MPS11_BUCK9_RAMP_SHIFT and S2MPS11_BUCK6_RAMP_EN_SHIFT are 0. Signed-off-by: Axel Lin <axel.lin@ingics.com> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
