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.
