Documentation: gpio: fix function links in the HTML docs
The shorthand [_data] and [devm_] cause the HTML documentation to not
link to the function documentation properly. This expands the references
to the complete function names with the exception of
devm_gpiochip_remove() which was dropped by commit 48207d7595
("gpio:
drop devm_gpiochip_remove()").

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[_data]()`` or ``devm_gpiochip_add_data()``.

Removing a GPIO controller should be rare; use ``[devm_]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.

If there is a need to exclude certain GPIO lines from the IRQ domain handled by

these helpers, we can set .irq.need_valid_mask of the gpiochip before
|

``[devm_]gpiochip_add_data()`` is called. This allocates an .irq.valid_mask with as

many bits set as there are GPIO lines in the chip, each bit representing line

0..n-1. Drivers can exclude GPIO lines by clearing bits from this mask. The mask

must be filled in before gpiochip_irqchip_add() or gpiochip_irqchip_add_nested()

is called.
