tpm: TPM 2.0 CRB Interface

tpm_crb is a driver for TPM 2.0 Command Response Buffer (CRB) Interface
as defined in PC Client Platform TPM Profile (PTP) Specification.

Only polling and single locality is supported as these are the limitations
of the available hardware, Platform Trust Techonlogy (PTT) in Haswell
CPUs.

The driver always applies CRB with ACPI start because PTT reports using
only ACPI start as start method but as a result of my testing it requires
also CRB start.

tpm: TPM 2.0 FIFO Interface

Detect TPM 2.0 by using the extended STS (STS3) register. For TPM 2.0,
instead of calling tpm_get_timeouts(), assign duration and timeout
values defined in the TPM 2.0 PTP specification.
