ENGR00133551-2 Add fastboot driver support for android.

Add fastboot driver support for android. In this commit,
basic fastboot command is supported.
1) Reboot board
   >fastboot reboot
2) Get information of board, e.g, product name
   >fastboot getvar product
3) Download images in PC and flash to SD card
   >fastboot flash bootloader u-boot-no-padding.bin
   >fastboot flash kernel uImage
   >fastboot flash uramdisk uramdisk.img
   >fastboot flash system system.img
   >fastboot flash recovery recovery.img
Certainly, SD card must have been formatted as Android user
guider doc already.
