Add an implementation of a TPM TIS driver

This patch adds an implementation of a TPM TIS driver for the TPM TIS
emulation supported by QEMU. The driver is broken up into several
small functions that have to be called in proper sequence. The driver is
cleanly separated from the rest of the code through an interface holding
pointers to the driver's functions.
A client using this driver first probes whether the TPM TIS
interface is available (probe function) and then invokes the interface
function to initialze the interface and send requests and receive responses.

Possible future extensions *could* include a virtio interface for the TPM
with a corresponding driver here.
