增加暗码命令切换开关机logo功能
u-boot logo显示原理：
1.————Little Kernel会在platform_early_init阶段首先会获取lcm params，其工作流
程就是透过读id找到现在插入的LCM，根据LCM的分辨率申请相应大小的frame buffer
并确定frame buffer起始地址
2. 为logo.bin预留4M Ram
3. 之后在platform_init阶段，直接将logo.bin载入到4M Ram中
4, 完成载入后，在platform_init中mt_disp_show_boot_logo();会调用
show_logo(0);完成第一张logo显示。其中的index=0代表在logo.bin中压缩的第一张
图片，logo.bin中的图片压缩顺序可以察看文件
mediatek\custom\common\lk\logo\rules.mk
2.————4.2的kernel logo显示原理：
Kernel logo的工作方式与U-boot logo不同，是透过init.rc中注册的
boot_logo_updater service完成读取raw data文件，进行绘画的，所以在kernel
logo只是经过了bmp向raw的转换，在目录mediatek\custom\common\lk\logo\下生成
raw data 文件boot_logo。之后透过脚本文件将boot_logo文件搬移到
out\target\product\xxxx\system\media\images下，打包为system.img，download
到手机种，并存放于/system/media/images目录下。
3.————4.2对于ipo快速开机，请在目录mediatek\external\ipod\bootlogo.cpp中的
mt65xx_disp_show_boot_logo();做相应修改
4.————4.4的kernel logo和ipo快速开机用的是同一个接口。
在boot_logo_updater.c的main中与4.2的方法不同使用了show_kernel_logo函数调用
显示了包在logo.bin中的kernel.logo，修改方法可以在alps\mediatek\external\libshowlogo\charging_animation.cpp
中对这部分代码进行尝试读取nv显示修改，kernel层的logoindex可以查看文件
mediatek\custom\common\lk\logo\rules.mk中kernel.bmp的顺序
void show_kernel_logo()
{
LOG_ANIM("[charging_animation: %s %d]show kernel logo, index = 38 \n",__FUNCTION__,__LINE__);
if (error_flag == 0)
{
anim_show_logo(kernel_logo_position);
}
}
由于快速开关机部分alps\mediatek\external\ipod\bootlogo.cpp
也是使用了此接口，若添加，应该就可以做到暗码修改了。
对于U-boot logo，只需要将不同分辨率的图片压缩至logo.bin中，在读取时根据不
同的NVflag显示相应的图片即可
而对于Kernel logo，我们需要将不同分辨率的boot_logo raw data文件生成出来并
copy到手机中，boot_logo_updater根据不同的分辨率进行识别，读取相应的logo文
件。在boot_logo_updater识别部分对NVflag进行判断，进而调用不同的boot_logo。
一、主要修改文件：
1.mediatek/external.git
boot_logo_custom这部分代码在4.4上是没有编译的，所以不用增加这部分的编译机制
这部分的logo是动画之前的那个logo,可以使用adb shell，cd 到/system/bin，执行
boot_logo_updater查看这个logo具体是哪张图片

解释下为什么mt_logo.c下的logo图片都是数字？这就要说明下little kernel的启动原理：
1. Little Kernel会在platform_early_init阶段首先会获取lcm params，其工作流
程就是透过读id找到现在插入的LCM，根据LCM的分辨率申请相应大小的frame buffer
并确定frame buffer起始地址
2. 为logo.bin预留4M Ram
3. 之后在platform_init阶段，直接将logo.bin载入到4M Ram中
4, 完成载入后，在platform_init中mt_disp_show_boot_logo();会调用
show_logo(0);完成第一张logo显示。其中的index=0代表在logo.bin中压缩的第一张
图片，logo.bin中的图片压缩顺序可以察看文件

A packages/apps/Contacts/src/com/mediatek/contacts/NvRAMAgent.java
这个文件是生成出来的，可以不用增加
packages/apps/Contacts/src/com/mediatek/contacts/SpecialCharSequenceMgrProxy.java
这个文件主要就是写入的暗码修改命令
针对不同的读取状态，进行状态切换
