gpio: em: use devm_platform_ioremap_resource()
There's no need to use the nocache variant of ioremap(). Switch to using devm_platform_ioremap_resource(). Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>
