All the default durations were being set to 10 minutes which is

Further, these are just the default, tpm_get_timeouts will set
them to values from the TPM (or throw an error).

Just remove them.

Sounds sensible.

Daniel?

Also sounds good to me. I believe this was just a remnant of the old
xen-tpmfront code that didn't get removed once the timeouts were being
read from the backend.
