vboot: allow for non-memory-mapped VBOOT regions
Depending on the platform the underlying regions vboot requires
may not be accessible through a memory-mapped interface. Allow
for non-memory-mapped regions by providing a region request
abstraction. There is then only a few touch points in the code to
provide compile-time decision making no how to obtain a region.
For the vblocks a temporary area is allocated from cbmem. They
are then read from the SPI into the temporarily buffer.
BUG=chrome-os-partner:27094
BRANCH=None
TEST=Built and booted a rambi with vboot verification.
