regulator: anatop: Fix wrong mask used in anatop_get_voltage_sel
The mask used in anatop_get_voltage_sel does not match the mask used in anatop_set_voltage_sel. We need to do left shift anatop_reg->vol_bit_shift bits for the correct mask. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
