util/ifdtool: Correct region resize handling
When regions are resized they are always aligned to the top of the
region. For the BIOS region this is correct. The other regions however
should be aligned to the bottom of the region.
Update the region handling to only align BIOS region to top of region.
BUG=N/A
TEST=verified image resize
