Subject: [PATCH v2] power_supply: bq24735: Convert to using managed resources
Use managed resource functions like devm_kasprintf and
devm_power_supply_register in bq24735_charger_probe. To be
compatible with the change, replace various gotos by direct
returns and drop unneeded labels.
Also, remove bq24735_charger_remove as it is now redundant.

Changes since v2:
- Use devm_power_supply_register
- Remove bq24735_charger_remove
