Code which compiles against fwlib2 no longer knows or cares about the
new data structures. This should shrink fwlib2 a bit. This is part 3
of 4 changes which split vboot 2.0 struct handling (old vboot1
structs) from vboot 2.1 struct handling (new style structs).
No functional changes; just shuffling around code.
BUG=chromium:423882
BRANCH=none
TEST=make runtests && VBOOT2=1 make runtests (works with/withoug VBOOT2 flag)
And compile firmware for veyron_pinky.
