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

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

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.
