regulator: twl6030: fix get status of twl6032 regulators

[ Upstream commit 31a6297b89aabc81b274c093a308a7f5b55081a7 ]

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.
