ccd: add 'in progress' return value
Depending on device configuration and compile time options, CCD
commands 'open' and 'unlock' could either be executed immediately, or
require the user to take the device through physical presence state
machine.
As these commands execute through TPM vendor commands, there needs to
be a different return value indicating that the command action is not
finished and PP process is in progress.
Let's add another vendor command return value, and do not consider it
a failure if vendor command returns this value in response to 'ccd
open' or 'ccd unlock'.
BRANCH=cr50
BUG=b:62537474
TEST=took an Eve through 'ccd open' sequence
