[PATCH 1/6] drm/fbdev-generic: Always use shadow buffering

Remove all codepaths that implement fbdev output directly on GEM buffers. Always allocate a shadow buffer in system memory and set up deferred I/O for mmap. The fbdev code that operated directly on GEM buffers was used by drivers based on GEM DMA helpers. Those drivers have been migrated to use fb
