Cr50: Bump the watchdog timeout up a bit
Wiping and restarting the TPM, including regenerating the
endorsement certs can take over a second. The default watchdog
timeout is only 1.6 seconds, so let's make sure we don't
accidentally hit that limit.
BUG=chrome-os-partner:59902
BRANCH=none
TEST=make buildall; run on Reef
It wasn't firing before; it's still not firing.
