The behind-the-scenes manipulation of the per-plane DRM properties needs to be augmented with some singleton property assignments too (what CRTC should the connector be driving? what mode should be used? is the CRC on?). Also use DRM_MODE_ATOMIC_ALLOW_MODESET in the live commit in case the new configuration doesn't match with whatever set of modes and color formats the previous DRM master happened to use.
