To complete the decoupling of the DRM device from the zynqmp_dpsub, group all DRM-related structures in a zynqmp_dpsub_drm structure and allocate it separately from the zynqmp_dpsub. The DRM managed allocation of the drm_device now doesn't cover the zynqmp_dpsub anymore, so we need to register a cleanup action to release the zynqmp_dpsub when the drm_device is released. The will allow usage of the DisplayPort encoder as a standalone bridge, without registering a DRM device in this driver. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
