spring: update board revision info for DVT2

Including DVT2 in board revision IDs.

The board revision read from the GPIOs is encoded in ternary
(Z=0, LO=1, HI=2), so use the same encoding in the software and
re-order the id map to follow that ternary order.

BRANCH=spring
BUG=chrome-os-partner:19926
TEST=on Spring EVT, run "mosys platform version" and
"mosys memory spd print id"
