定制七：关闭双击 Power 打开 Camera 功能

环境：
[Android6.0][RK3399]

RK 平台默认“很贴心”的实现了一个双击 Power 键可以打开 Camera 的功能。
但是我根本就不需要啊 混蛋～
有时候手抖按了两下 Power 键就进入 Camera 了还得退出来真的很影响用户体验。
所以那就去掉这个功能吧。

代码实现：

diff --git a/packages/SettingsProvider/res/values/defaults.xml b/packages/SettingsProvider/res/values/defaults.xml
index e7949b8..607818d 100755
--- a/packages/SettingsProvider/res/values/defaults.xml
