[PATCH v4 06/10] qemu_validate.c: add validation for TPM Proxy model

Previous patch handled the conversion of def->tpm to the array def->tpms. What we're missing now is the validation code to make the VIR_DOMAIN_TPM_MODEL_SPAPR_PROXY model exclusive to PPC64 guests and VIR_DOMAIN_TPM_TYPE_PASSTHROUGH backend.
