Subject: [PATCH 10/14] gpio: max77650: use value returning setters

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

struct gpio_chip now has additional variants of the set(_multiple)
driver callbacks that return an integer to indicate success or failure.
Convert the driver to using them.
