Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports
damage handling, which is required by rz-du. Avoids the overhead of
fbdev-generic's additional shadow buffering. No functional changes.

Thanks a lot.

I just noticed that the drivers under renesas/ don't require damage 
handling, so the commit message needs a change.

Best regards
