Fix a badly reverted commit. The revert commit was cherry-picked from
drm-misc-next to drm-misc-next-fixes, and in the process some unrelated
code was added.

Fixes: a3fb64c00d44 "Revert "gpu/drm: ingenic: Add option to mmap GEM buffers cached""

I applied the patch to drm-misc-next-fixes.

Thanks,
