Commit 2527ecc9195e9 ("gpio: Fix OF build problem on UM") added the
dependency on HAS_IOMEM to OF_GPIO to address a build-issue on UML (User
Mode Linux). It's no longer needed as now UM defines stubs for
ioremap() and iounmap() even with !HAS_IOMEM (and its emulation can also
be enabled on UM now). Let's remove it.
