This patch adds a TIS device model compliant to the 1.2 TPM
specification to Qemu. It implements all registers necessary to make the
Linux TIS driver work (tpm_tis.c).
All of the basic registers supported by this type of device are
implemented. Also the locality selection has been implemented, but has
not been tested. The legacy registers as described in the specification
are not supported.

Current caveat: The device has so far not yet been integrated with the
virtual TPM available in the repository. It will require changes to the
virtual TPM spawned by the vTPM manager to offer an additional message
interface. The TIS interface itself then needs to have an additional
transport implemented. (see vTPMTransmit array).

The relevant specification for the device model can be found here:
