[Keith Short (Code Review)]

Hello Duncan Laurie, build bot (Jenkins), Martin Roth,

I'd like you to reexamine a change. Please visit

src/security/tpm: query recovery mode from Cr50

On the Sarien/Arcada platforms, the EC is not trusted to provide
the state of the ESC+REFRESH+PWR recovery combination. On these
platforms the Cr50 latches the state of REFRESH+PWR for use as the
recovery mode key combination.

BUG=b:122715254
BRANCH=none
TEST=Verify recovery mode screen shown after pressing REFRESH+PWR
