Fixed it by defining rockchip_dp_dt_ids[] under CONFIG_OF.
I think the __maybe_unused annotation is generally preferred over
#ifdefs these days. However, since these drivers only work with
devicetree anyway, it probably makes more sense to just remove the
of_match_ptr() uses which lead to these warnings in the first place.
