sysupgrade: Add SBL_NAND_PREAMBLE if preamble bytes exist in image
Now we are adding preamble value to read SBL header if ubi section
is present in the image. But in case of NOR+NAND images, though we are
having SBL in NOR and ubi section is also present and NAND_PREAMBLE
is getting added. which is breaking NOR+NAND sysupgrade.
Added functionality to compare first 12 bytes of section with pre
defined PREAMBLE value. If values matches, add the NAND_PREAMBLE to
read SBL header.
