4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Walleij <linus.walleij@linaro.org>
commit 2527ecc9195e9c66252af24c4689e8a67cd4ccb9 upstream.
The UserMode (UM) Linux build was failing in gpiolib-of as it requires ioremap()/iounmap() to exist, which is absent from UM. The non-existence of IO memory is negatively defined as CONFIG_NO_IOMEM which means we need to depend on HAS_IOMEM.
