Kernel test robot throws below warning when CONFIG_OF
is not set.
>> drivers/gpu/drm/rockchip/analogix_dp-rockchip.c:457:34:
warning: unused variable 'rockchip_dp_dt_ids' [-Wunused-const-variable]
static const struct of_device_id rockchip_dp_dt_ids[] = {
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.

Ok. Will remove of_match_ptr().
