The implementation of the plane's call-back functions prepare_fb() and
cleanup_fb() for GEM VRAM helpers are sharable among drivers.
Patch #3 also fixes two bugs that have been present in hibmc since it was
first added. The primary plane's atomic_update() is not responsible for
pinning BOs. And it never unpinned unused BOs. VRAM is being exausted
over time.
The new helpers have been tested to work.
v2:
* provide helpers for struct drm_simple_display_pipe_funcs, and...
* ...use them in bochs
