该模块是系统睡眠，锁存在的时候系统无法休眠
验证是否在睡眠状态，则需要测试功耗
电源管理原则，只要有一个wakelock锁存在，系统就不会进入Suspend状态
所以名字可以随便取，表示需要这样的一个锁，所以系统就不会进行睡眠

/*
例如AT*POWERIND=31，就相当于设置NETWORK、SIM、SMS、CS CALL、PS DATA变化时都不主动上报，
其中PS DATA目前暂时不支持，只是保留了这个标志位；
AP power state: 1~31 means suspend, bitmap: bit0 - NETWORK;bit1 - SIM;bit2 - SMS;bit3 - CS CALL;bit4 - PS DATA
0 means resume all.
目标文件"/system/etc/powerind"
如果bit0-bit3都配置可以采用的值是1-15，如果是当前采用NETWORK SMS CALL 则值的取值是 1 4 8 5 9 12 13


白名单的状态由四位数字组成，第一位代表是否屏蔽电话唤醒，第二
位代表是否屏蔽网络注册状态唤醒，第三位代表是否屏蔽数据业务唤
醒，第四位代表是否屏蔽短信唤醒。其中 1 代表屏蔽，其他不会屏
蔽。
第一位：1：打开电话唤醒，其他：屏蔽电话唤醒
第二位：1：打开网络注册状态唤醒，其他：屏蔽网络注册状态唤醒
第三位：1：打开数据业务唤醒，其他：屏蔽数据业务唤醒
第四位：1：打开短信唤醒，其他屏蔽短信唤醒
当四位都不为 1 时（比如默认的状态：0000），则代表白名单为空，
所有唤醒都不会屏蔽。

从左往右判断
