[PATCH] drm/rockchip: defined struct rockchip_dp_dt_ids[] under CONFIG_OF

[Souptick Joarder]

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.
