增加HIDL接口manifest后编译报错如下：

INCOMPATIBLE
根据kernel版本，用的是compatibility_matrix.5.xml （FCM Version 5）
而compatibility_matrix.5.xml中定义的gnss version是2.0-1
<hal format="hidl" optional="true">
<name>android.hardware.gnss</name>
<version>2.0-1</version>
<interface>
<name>IGnss</name>
<instance>default</instance>
</interface>
</hal>
有两种解决方法：
1：把gnss service改成用2.0或2.1的版本
2：把compatibility_matrix.5.xml 中2.0-1 改成1.0
