drivers/tpm: add xen tpmfront interface
This is a complete rewrite of the Xen TPM frontend driver, taking
advantage of a simplified frontend/backend interface and adding support
for cancellation and timeouts. The backend for this driver is provided
by a vTPM stub domain using the interface in Xen 4.3.
