drm: arcpgu: Fix mmap() callback
Now that ARC properly supports DMA mmap() we can use the standard CMA helper to map dumb buffers. This makes ARC PGU works with standard DRM consumer applications like, for example, mpv/mplayer via DRM. While at it, use the DEFINE_DRM_GEM_CMA_FOPS() helper. This fixes the use of dumb buffers.
