MLK-12527-3 android: Add board support to enable android fastboot

Add board level support for android fastboot feature. Each board has
a android specified header file for defining android related configuraitons.
And add build targets for their android uboot images building.

For mx6qsabreauto, mx6sabresd and mx7dsabresd, we enable the android
fastboot exclusive with DFU.
