命名规范：修改少量Arch接口，命名规范化调整： 1.修改arch/include下接口声明，所有arch对外提供调用函数均以ArchXX命名 2.提取多个架构均有实现的公共函数声明至arch/include对应头文件中以供外部调用，并修改命名格式为ArchXX 3.修改OS_HWI_WITH_ARG为LOSCFG_PLATFORM_HWI_WITH_ARG并移至los_config.h中 4.typedef VOID (*OS_TICK_HANDLER)(VOID);暂时移至arch/include/los_timer.h中 5.实现atomic原子操作相关接口，位于arch/include/los_atomic.h,arm架构部分与汇编指令相关原子操作接口使用ARCH_ARM宏进行控制是否编译 BREAKING CHANGE: 1.修改arch/include下接口，以ArchXX命名函数 2.提取公共函数声明:ArchAtomicXchg32bits、ArchAtomicDecRet、ArchAtomicCmpXchg32bits 3.新增部分原子操作c内联实现 Close #I4N7XV Signed-off-by: LiteOS2021 <dinglu@huawei.com>
