* QEMU: add TPM Proxy device support
libvirt can now create guests using a new device type called
"TPM Proxy". The TPM Proxy connects to a TPM Resource Manager
present in the host, enabling the guest to run in secure virtual
machine mode with the help of an Ultravisor. Adding a TPM Proxy to
a pSeries guest brings no security benefits unless the guest is
running on a PPC64 host that has Ultravisor and TPM Resource Manager
support. Only one TPM Proxy is allowed per guest. A guest using
a TPM Proxy device can instantiate another TPM device at the same
time. This device is supported only for pSeries guests via the new
'spapr-tpm-proxy' model of the TPM 'passthrough' backend.
