cr50: vendor command to enable nvmem commits
TPM NVMEM commits are reenabled as soon as the system boots into
Chrome OS. However, sometimes the device does not boot into Chrome OS,
in which case it is necessary to be able to reinstate NVMEM commits
explicitly.
The new vendor command will provide this functionality.
BRANCH=none
BUG=chrome-os-partner:59873
TEST=added code to depthcharge to issue the new vendor command if the
system falls into recovery mode, verify that commits are
re-instated once the command is issued.
