如何打开SPI功能
[Solution]
在\mediatek\config\<project>\autoconfig\kconfig\project或
\mediatek\config\<project>\autoconfig\kconfig\platform文件中添加以下内容：

注意：
–SPI 配置依赖的比较复杂，不能直接修改project打开SPI。需要将以上内容均拷贝过来
–project产生的配置文件依赖于两个，
•平台相关：
alps/mediatek/config/<platform>/autoconfig/kconfig/platform
•project相关：
alps/mediatek/config/<project>/autoconfig/kconfig/project
