Subject: [PATCH] drm/rockchip: defined struct vop_driver_dt_match[] under CONFIG_OF

kernel test robot throws warning when CONFIG_OF not set.

>> drivers/gpu/drm/rockchip/rockchip_vop_reg.c:1038:34:
warning: unused variable 'vop_driver_dt_match' [-Wunused-const-variable]
   static const struct of_device_id vop_driver_dt_match[] = {

Fixed it by defining vop_driver_dt_match[] under CONFIG_OF.
