[Haneen Mohammed]

This patchset add the necessary infrastructure needed later for CRC
support.

1. add functions to map buffers to kernel address space.
2. map/unmap buffers in the prepare/cleanup_fb hooks.
3. clip plane coordinates.
4. subclass CRTC state.

changes in v4:
- drop patch 5 "drm/vkms: Implement CRC debugfs API" from this patchset
since it needs further work.
