extcon: palmas: Use devm_extcon_dev_register()
Use the resource-managed extcon device register function (i.e. devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device is attached with this function, that extcon device is automatically unregistered on driver detach. That reduces tiresome managing code.
