TPM locality capability

TPMs are not guaranteed to have additional localities. If I recall correctly, the TCG PTP specification defines a bit in the interface ID register which indicates if further localities are available.

For example, at least Intel PTT on Skylake (presumably Kabylake as well) does not have additional localities.
