Subject: power: supply: bq27xxx_battery: Fix register map for BQ27510 and BQ27520

From: Andrew F. Davis <[email protected]>

commit 3bee9ea1de687925d116670f036599cbed8b66b0 upstream.

The BQ27510 and BQ27520 use a slightly different register map than the BQ27500, add a new type enum and add these gauges to it.

Fixes d74534c27775 ("power: bq27xxx_battery: Add support for additional bq27xxx family devices")
