exynos: Install the BL1 and set the checksum in the Makefile.
Install the BL1 and set up the checksum in the Makefile instead of relying on
post processing. Import the exynos checksum script, split it in two and
simplify it significantly. Stop putting the CBFS header in the midst of the
bootblock so that it can be checksummed before CBFS is put together. Stop
saving space for it and leaving an anchor in the bootblock which nobody looks
for.
