[PATCH 5.15.y 1/2] gpio: sch: use new GPIO line value setter callbacks

[Sasha Levin <sashal@kernel.org>]

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

[ Upstream commit 883c7eb2c4a9e143b2662ba754f9c16fb31adced ]

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