Android SystemUI去掉拖动亮度条QSPanel界面隐藏功能

SystemUI的在下拉状态栏第二次展开的QSPanel的界面时，原生下拉状态栏界面会有亮度条SeekBar，

当拖动的时候，亮度会改变但是同时整个QSPanel下拉状态栏也隐藏掉了 。客户要求去掉这个拖动亮度条时隐藏下拉状态栏的功能

相关布局和代码

```
 
/SystemUI/res/layout/quick_settings_brightness_dialog.xml 亮度条核心布局
 
/SystemUI/res/layout/brightness_mirror.xml 包含亮度条布局
 
/SystemUI/res/layout/qs_panel.xml 下拉状态栏第二次展开的QSPanel的界面
