高通8150-SSC架构如何去掉hall sensor使之不编译进slpi

说明：项目需求:由于项目没有使用到Hall sensor,因此不需要QSensorTest的APK上显示hall sensor相关的信息。

一、相关的修改如下,

二、重新编译slpi，查看sns_static_sensors.c这个文件是否将hall sensor的注册函数删除，下面是编译后的结果已经将hall sensor注册的接口删掉了。

三、将编译生成的modem镜像烧录系统，在系统启动之后运行如下命令：sns_hal_batch.

修改之前运行sns_hal_batch.的结果，查看是有:bu52053nvx Hall Effect Sensor 相关信息

修改之后运行sns_hal_batch.的结果，查看没有hall sensor的相关信息，修改成功。
