PATCH 1/1 power: supply: bq27xxx_battery: Fix register map for BQ27510 and BQ27520

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")

This function should be converted to switch/case blocks... those if/or/return conditions are now too big.

Queued into for-next. I think pali's hint, that bq27xxx_battery_overtemp() should be implemented using a switch-case is valid to make the code more readable. Please provide this change as follow-up patch.

I think there may be better ways than even switch-case, perhaps we can add additional info flags to the part's description tables, then just branch on that for each accessor type.

Anyway, I'll see what I can to to clean this up when I get some bandwidth.

Thanks,
Andrew
