struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

This driver was not queued via the pinctrl tree as it should so it flew
under my radar and it uses a deprecated interface that we *really* want
to remove in v6.17. This patch addresses it. I would really appreciate
it if it could be queued on top of the SoC tree before the merge window.
Arnd: could you take it directly?
