[ Upstream commit b67fdcb7099e9c640bad625c4dd6399debb3376a ]
Commit cd060b4d0868 ("power: supply: bq27xxx: fix polarity of current_now") changed the sign of current_now for all bq27xxx variants, but on BQ28Z610 I'm now seeing negated values *with* that patch.
The GTA04/Openmoko device that was used for testing uses a BQ27000 or BQ27010 IC, so I assume only the BQ27XXX_O_ZERO code path was incorrect. Revert the behaviour for newer ICs.
