Fix TPM driver to work with multiple vendor TPMs

Port u-boot patch for low-level driver:
    - Fix bug in traversal of vendor name list.
    - Sending "command ready" needs additional logic to handle
    TPMs that need that bit set twice: once to empty the read
    FIFOs and once to actualy set command ready.
