The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.
