WIP: move Linux frame buffer support to base system

[wulf7]

On Linux, framebuffer code is not a part of drm and can be used with non-drm drivers. The aim is to move linux_fb.c vt_drmfb.c to linuxkpi_video module and import to base system after than. The changes clashes with ongoing drm-kmod 6.xx import doing by @dumbbell. That should be resolved in future. Still WIP

Would be good to also indicate why they should be in the base system

We a going to make drm.ko to be a part of base system

On Linux, framebuffer code is not a part of drm and can be used with non-drm drivers.

This isn't completely true anymore, now that SimpleDRM is a thing and distros have largely replaced the traditional framebuffer with the DRM backed one.
