Michael Tsirkin previously requested that there be an option for the TPM
passthrough driver to be selectively enabled since at least using
/dev/tpm0 may not be what everybody wants. The passthrough driver at
some point will also be able to use sockets to communicate with a TPM
when a file descriptor is passed to Qemu, so maybe that changes then?
