mtk利用nvram分区进行多屏兼容方案
1. 参考
[FAQ11409]通过预设在nvram里的数据实现lcm兼容的方案
2. 可以利用MTK工具SP_META去修改nvram分区，（注意：SP_META工具选择的数据库文件路径如下）
3. mtk的FAQ修改方法只适用Android4.x版本的。下面是MT6735-Android5.1上，自己实现的具体修改记录
bootable修改：
通过mtk SP_META去修改nvram分区（该分区包括了64字节的barcode、40字节IMEI），现在开辟了跟在barcode和IMEI的4个字节作为lcd识别区，不过只用了一个字节去区别屏，例如0x30就调用lcd0、0x31就调用lcd1...
