Furquan Shaikh e7f35cd292 ifwitool: Do not calculate checksum for subpart_dir
1. The checksum method that was documented is not correct. So, no use
filling in a value based on wrong calculations. This can be added back
once updated information is available.
2. Checksum does not seem to affect the booting up of SoC. So, fill in 0
for now.

Furquan Shaikh fe42b11cdf ifwitool: Correct pack order and header order
Update pack and header order and mark the entries as mandatory and
recommended w.r.t. ordering (mandatory = essential for booting,
recommended = okay to change, but this config is tested and known to work).
