SPL: EXYNOS: Prepare for variable size SPL support
When variable size SPL is used, the BL1 expects the SPL to be
encapsulated differently: instead of putting the checksum at a fixed
offset in the SPL blob, prepend the blob with a header including the
size and the checksum.
The enhancements include
- adding a command line option, '--vs' to indicate the need for the
variable size encapsulation
- padding the fixed size encapsulated blob with 0xff instead of random
memory contents
- do not silently truncate the input file, report error instead
- no need to explicitly closing files/freeing memory, this all happens
on exit; removing cleanups it makes code clearer
- profuse commenting
- modify Makefile to allow enabling the new feature per board
