[PATCH v2 08/10] sandbox: tpm: Support storing device state in tpm2

[Simon Glass]

At present the tpm2 emulator does not support storing the device state.
Add this so we can handle the normal vboot flow through the sandbox
executables (VPL->SPL etc.) with the TPM contents staying in place.

Note: sandbox has not yet been converted to use livetree for the state
information, since livetree does not yet support writing to the tree.
