regulator: twl6030: do not write to _GRP for regulator enable
TWL6030: regulator is enabled via VREG_STATE TWL4030: regulator is enabled via VREG_GRP Since there is nothing common, split twlreg_enable similar to other regulator_ops Signed-off-by: Balaji T K <balajitk@ti.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
