drm/rockchip: add CONFIG_OF dependency

DRM_DISPLAY_DP_AUX_BUS cannot be selected when CONFIG_OF is disabled:

WARNING: unmet direct dependencies detected for DRM_DISPLAY_DP_AUX_BUS
  Depends on [n]: HAS_IOMEM [=y] && DRM [=y] && OF [=n]
  Selected by [y]:
  - DRM_ROCKCHIP [=y] && HAS_IOMEM [=y] && DRM [=y] && ROCKCHIP_IOMMU [=y] && ROCKCHIP_ANALOGIX_DP [=y]

Rockchip platforms all depend on OF anyway, so add the dependency here
for compile testing.
