[PATCH v5 5/9] drm/mediatek: Add get_sec_port interface to mtk_ddp_comp

[Shawn Sung]

From: "Jason-JH.Lin" <jason-jh....@mediatek.com>

Add get_sec_port interface to ddp_comp to get the secure port settings
from ovl and ovl_adaptor.
Then mediatek-drm will use secure cmdq driver to configure DRAM access
permission in secure world by their secure port settings.
