标题: rk3568 openharmony 6.1双摄像头（前后摄）camera_host_config.hcs要如何配置，相机应用才能看到2个摄像头，并能够来回切换？
[md]### 【问题描述】

1. 介绍问题现象和发生的背景
2个gc05a2 sensor，前后摄，目前无法在相机应用中看到2个摄像头并能来回切
2. 相关的代码（请勿使用截图）

sensor均正常识别到，且在android11系统下，板子所有硬件都已经调通，包括双sensor，在android的相机应用中可以正常看到2个摄像头并正常切换
4. 我尝试过的解决方法和结果

反复调整camera_host_config.hcs文件，均无法实现
5. 我想要达到的结果

能够在相机应用上看到2个摄像头，且能正常切换
