Randall Spangler 00b344ddbb Clean up vboot hash support
This copies the parts of sha256.c that we need from vboot_reference,
and removes the explicit dependency on vboot_reference.  That
dependency was a good idea when we were doing full verified boot in
the EC, but is now overkill and makes it harder for others to reuse
the EC code.  This also lets us call EC functions directly instead of
needing vboot_stub.cc; that reduces code size by ~100 bytes.

BUG=chrome-os-partner:15579
BRANCH=none
TEST=vboot_hash ro, then compare with result of sha256sum build/link/ec.RO.flat
