This series cleans up tpm timeouts setting and handling.

First motivation was to fix failures coming from too short timeouts
for commands that creates keys.
Key generation may take significant time depending on the underlying
hardware. Rather than increasing default timeout a new constant is
added, to not stall too long on regular commands failures.

Second is to define timeouts for new tpm2 commands
defined in TCG 1.36 spec.
Probably a typo, since the latest TCG spec version is the 1.38 [0].
 
Where can we get that specification? I don't have that new
version and couldn't find it from the public internet.
