gpio: 74xx-mmio: Use devm_gpiochip_add_data() for gpio registration
Use devm_gpiochip_add_data() for GPIO registration and remove the call for gpiochip_remove() from error path. Also remove the need of driver callback .remove. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Cc: Alexander Shiyan <shc_work@mail.ru>
