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

You can specify another config file in hb build like this:
  hb build --gn-args liteos_config_file=myconfig.config
file specified in liteos_config_file argument is relative
to "$product_path/kernel_configs" directory, or is an
absolute file path, for example:
  hb build --gn-args liteos_config_file=//path/to/myconfig.config
or
  hb build --gn-args liteos_config_file=/another/path/to/myconfig.config
