regulator: twl6030: fix get status of twl6032 regulators

[ Upstream commit b188d2b0155cf04783fc1da80e4aa5b389623924 ]

Status is reported as always off in the 6032 case. Status
reporting now matches the logic in the setters. Once of
the differences to the 6030 is that there are no groups,
therefore the state needs to be read out in the lower bits.
