drm/komeda: Add legacy FB support so VT's work as expected

The komeda driver doesn't come up with a visible text (FB) mode VT by
default as it was missing legacy FB support. It's useful to have a
working text VT on a system for debug and general usability, so enable
it. You can always toggle CONFIG_FRAMEBUFFER_CONSOLE.
