gpio: Fix OF build problem on UM

[ Upstream commit 2527ecc9195e9c66252af24c4689e8a67cd4ccb9 ]

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.
