Laxman Dewangan 0cf3292cde 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.
