regulator: max8973: Don't override control1 variable when set ramp delay bits
Current code overrides control1 variable when setting ramp delay bits. Fix it by just setting ramp_delay bits. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
