To enable the virtual terminal layer with virtio-gpu, we need to
provide the dummy console. This console is hidden behind CONFIG_IOMEM
via the graphics support. Instead of fully enabling the graphic
drivers lets just provide a Kconfig option for the dummy console.

New version: instead of moving around the graphic and console stuff,
let's just keep an s390 specific variant of CONFIG_DUMMY_CONSOLE

You already have your own copy of HAS_IOMEM, which makes it hard for
people to track which one applies where.
I think I agree with Geert - let's better fix this in a proper way
instead of doing hacks like this. I guess there will be other
architectures in the future that might want to use the dummy console
without CONFIG_IOMEM, so fixing this in drivers/video/ instead sounds
better to me.
The question is, what is the proper fix?
How about we only fence off sub menu items such as DRM or GPU or Fbdev, which
actually uses io memory, in drivers/video/Kconfig? Similar to what Thomas
suggested for moving the CONFIG_IOMEM dependency for fbdevs?
Can you spin a patch?
Yes, I will post it as V3.
