1.【需求描述】 L0 支持低功耗投票框架, 使内核与应用、驱动分离开，通过注册及投票机制控制系统的低功耗模式, 减低系统功耗,提升设备电池寿命。 2.【方案描述】 (1).提供注册机制，使驱动与内核分离 (2).提供投票机制，判断系统运行模式 (3).记录持锁设备，便于回溯 进入：系统运行进入idle任务时判断当前的功耗模式，如果上层应用未对当前功耗模式(deep和shutdown) 持锁，则系统准备进入当前模式,首先所有设备依次进入当前模式，如果有设备进入当前模式失败，则恢复 已进入当前模式的所有设备，并且功耗模式变为normal模式；设备依次进入当前功耗模式后cpu再进入当前 功耗模式。 恢复：功耗模式为deep时，需要恢复逻辑，时系统恢复运行。当有中断出发时，系统会退出低功耗模式， 恢复顺序为：首先cpu先恢复，然后设备依次恢复。 BREAKING CHANGE: 1.原调度中基于tick timer的低功耗扩展和当前的pm模块合并，删除原对外接口LOS_SchedSleepInit, 变为pm模块统一提供的LOS_PmRegistered接口. 2.原来在arch los_timer.h下提供的低功耗模式为枚举LOS_SysSleepEnum，其中OS_SYS_NORMAL_SLEEP 和OS_SYS_DEEP_SLEEP不符合对外定义，统一修改为LOS_SYS_NORMAL_SLEEP和LOS_SYS_DEEP_SLEEP, 并移至los_pm.h中. 3.VOID HalEnterSleep(LOS_SysSleepEnum sleep) 变更为UINT32 HalEnterSleep(VOID).
