refactor: 内核目录结构整理
1. 原kernel/common目录下属于内核拓展组件，统一移入kernel/extend管理 2. Kconfig分层，各模块自己的配置放到自己目录下管理 3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译 4. 对外公共头文件统一抽到对外include路径 5. 废弃宏，头文件清理 close: #I48KI4 Signed-off-by: arvinzzz <zhaotianyu9@huawei.com> Change-Id: I0cf5ea81c92a8fa7b113da9cbdc8b7bc935f5aae
