gpiolib: Remove data-less gpiochip_add() function
GPIO chips should be added with driver-private data associated with the chip. If none is needed, NULL can be used. All users already do this except one, fix that here. With no more users of the base gpiochip_add() we can drop this function so no more users show up later.

The code implementing a gpio_chip should support multiple instances of the

controller, preferably using the driver model. That code will configure each
|

gpio_chip and issue gpiochip_add(), gpiochip_add_data(), or
|

devm_gpiochip_add_data(). Removing a GPIO controller should be rare; use

gpiochip_remove() when it is unavoidable.

Often a gpio_chip is part of an instance-specific structure with states not

exposed by the GPIO interfaces, such as addressing, power management, and more.
