Subject: [PATCH v1 2/2] fbdev: Kconfig: Add HAS_IOMEM dependency for FB_OPENCORES

The Opencores framebuffer device uses I/O memory and with
CONFIG_HAS_IOMEM disabled will lead to build errors:

ERROR: "devm_ioremap_resource" [drivers/video/fbdev/ocfb.ko] undefined!

Fix this by adding HAS_IOMEM dependency for FB_OPENCORES.
