MLK-12527-2 android: Add FSL android fastboot support

Integrate the FSL android fastboot features into community's fastboot.

1. Use USB gadget g_dnl driver
2. Integrate the FSL SD/SATA/NAND flash operations, since the GPT and
   EFI partitions are not support by i.MX.
3. Add FDT support to community's android image.
4. Add a new boot command "boota" for android image boot. The boota
   implements to load ramdisk and fdt to their loading addresses
   specified in boot.img header, while bootm won't do it for android image.
5. Support the authentication of boot.img at the "load_addr" for
   both SD and NAND.
6. We use new configuration CONFIG_FSL_FASTBOOT for Freescale's fastboot
   with relevant header file "fsl_fastboot.h". While disabling the
   configuration, the community fastboot is used.
7. Overwrite the cmdline in boot.img by using bootargs saved in local environment.
8. Add recovery and reboot-bootloader support.
