[PATCH] gpio: xilinx: convert set_multiple() to the new API as well

[Bartosz Golaszewski <brgl@bgdev.pl>]

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

The patch converting the driver to using new GPIO line value setters
only converted the set() callback and missed set_multiple(). Fix it now.

Fixes: 1919ea19a4ff ("gpio: xilinx: use new GPIO line value setter callbacks")
