mb/google/volteer/variant/lindar: Disable SA GV for Samsung memory with wrong date code MB

Disable SA GV, because factory used Samsung memory with wrong date code.
So we need to use board version to identify build MB phase to disable SA GV.
Disable SA GV when board version equal one.

BUG=b:179747696
BRANCH=firmware-volteer-13672.B
TEST=Built and booted into OS.
