tpm: TPM2 support for tpm_calc_ordinal_durations()

Implemented TPM2 support for tpm_calc_ordinal_duration(). TPM2 version
is encapsulated into tpm2_calc_ordinal_duration() that is called by
tpm_calc_ordinal_duration() for TPM2 chips.

[jarkko.sakkinen: implemented tpm2_calc_ordinal_duration() based on
 the Wills original patch.]

tpm: TPM2 support for tpm_do_selftest()

Implemented tpm2_run_self_test() that runs the full (all commands)
test for the TPM chip. During the self test TPM2 commands return
with the TPM error code RC_TESTING. Waiting is done by issuing PCR
read until it executes succesfully or some other error condition
than RC_TESTING happens.
