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.
