mtk8175添加一款camera(GC5035)流程
说明：
在MTK平台添加一款新的Camera IC 需要如下三个步骤：
- device目录下面添加相关宏定义。
- kernel目录下面添加dts配置，即硬件管脚、时钟、电源、I2C等的配置和 添加相关的驱动。
- vendor 目录下面添加相关的效果文件。
下面是自己在MTK8175 kernel-4.14 android9.0中添加GC5035的记录，供参考

按照上述的修改，添加文件需找FAE提供。或者找个相近的替换先调通整个流程。
这样修改后全编译后，使用自带的camera2即可打开camera预览。
调试时可使用：
adb查看是否读到id
cat /proc/driver/camera_info
调试vendor下面代码时可打开日志
文件位置vendor/mediatek/proprietary/hardware/mtkcam/legacy/include/mtkcam/Log.h
把 1改成 4即可。
