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.
Note: This patchset was built on top of the following patchset: subject: [PATCH V2 0/5] drm/vkms: Updates to meet basic kms_flip requirements link: https://lists.freedesktop.org/archives/dri-devel/2018-June/180823.html
