We must not to adjust the port order, cause the port id is mapping
to VOP type. Current driver just hardcode that VOP Lit is ID 0, and
VOP Big is ID 1.

        ret = rockchip_drm_encoder_get_mux_id(dp->dev->of_node, encoder);
        if (ret)
                val = dp->data->lcdsel_lit | dp->data->lcdsel_mask;
        else
                val = dp->data->lcdsel_big | dp->data->lcdsel_mask;

Besides eDP could work well with VOP Lit, so we need to revert this
hack. Just revert commit 602f4f79c8f2a833069cd32cb0cc80984e6febb6.
