Subject: [PATCH 2/3] memory: mtk-smi: Add module_exit and module_license

The config MTK_SMI always depends on MTK_IOMMU which is built-in
currently. Thus we don't have module_exit before. This patch adds
module_exit and module_license. It is a preparing patch for supporting
MTK_SMI could been built as a module.
