feat: L0 支持低功耗框架

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).
