Original change's description:
> ozone/drm: Use minigbm mmap for modeset buffers
> 
> FillModesetBuffer assumed all the buffers could be mmaped as dumb
> buffers.
> This doesn't work on some platforms.
> 
> This CL mmaps the modeset buffer using gbm_map instead, that should
> work with tiled formats too.
