gpio: Add devm_ apis for gpiochip_add_data and gpiochip_remove
Add device managed APIs devm_gpiochip_add_data() and devm_gpiochip_remove() for the APIs gpiochip_add_data() and gpiochip_remove(). This helps in reducing code in error path and sometimes removal of .remove callback for driver unbind. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>
