ENGR00292902 ARM:imx6:sabresd/sabreauto Add android fastboot supporting

Support android features:
fastboot, booti command and recovery for sabresd SD, sabresd eMMC,
sabreauto SD, sabreauto NAND.

For all booting media (SD, eMMC, NAND), inherits the partitions layout
from v2009.08. Fastboot will detect the booting media to replace
hardcoding fastboot device. SATA is not supported.

FDT is supported to use the "unused" fields in bootimg header which
requires the FDT to be combined into the boot.img.
For non-FDT boot.img, the "unused" fields should left to NULL and is
compatible to boot.
