[PATCH 4/4] gpio: zynq: Simplify with of_device_get_match_data()

[Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>]

Driver's probe function matches against driver's of_device_id table,
where each entry has non-NULL match data, so of_match_node() can be
simplified with of_device_get_match_data().
