When using a TV as a display, output image may be cropped due to overscan. Rockchip VOP2 supports post-composition scaling in hardware, which can be used to compensate for the overscan.
This adds the necessary pixel margin fields to the CRTC state, and sets them from the TV overscan property of the connector which is understood by the userspace (tested with KWin's display configuration module).
