[RESEND PATCH] pinctrl: rp1: use new GPIO line value setter callbacks

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

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

Resending with linux-gpio correctly in Cc.

Another driver we missed, that should be the last one under
drivers/pinctrl/.

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?
