描述：qcm2290平台上，在低压充电阶段（XBL），需要驱动LED灯芯片，提供接口供充电模块调用，显示充电指示灯功能。
说明：LED控制芯片是I2C接口，我只需要提供接口即可，我这边实现了在开机时led灯闪烁，在充电相关PmicLib目录下添加灯效时i2c_api.h引用失败，所以将代码添加到了Display文件中。
配置如下：
在文件i2c_devcfg.c中已经定义好所有的i2c实例，只需要定义相应的宏控编译打开即可，使用的I2C SDA和SCL对应的gpio为gpio6和gpio7，需要在源文件中定义宏ENABLE_QUP_02。

以上是xbl阶段所有的修改，另外，还需要在TZ中打开I2C的权限配置
注意：I2C的权限配置不是qupv3_perms_default下，而在函数qupv3_perms_default_Genoa下配置（目前还没跟踪为啥是在这个函数下面），I2C的工作模式配置为FIFO
