drm/fb_cma_helper: Add drm_fb_cma_prepare_fb() helper
Add new drm_fb_cma_prepare_fb() helper function extracted from the imx-drm driver. This function checks if the plane has DMABUF attached to it, extracts the exclusive fence from it and attaches it to the plane state for the atomic helper to wait on it.
