The Opencores framebuffer device uses I/O memory and with

Fix this by adding HAS_IOMEM dependency for FB_OPENCORES.

I think it would be better if fbdevs in general would depend on
HAS_IOMEM ... or could there be any frame buffer devices without IOMEM ?
There are some small ones which are updated with, say, i2c
(ssd1307fb.c). I think those don't need iomem.

Most of the other framebuffer devices are fenced of by architecture
dependency or PCI dependency. So I am hesitant to introduce a blanket
dependency for all fbdevs.
Thank you guys for reviewing!
Thanks
