Added TPM SPI wait state support and debug logging.
Added platform auth ownership (change platform password to random value before boot).
Added parameter encryption support.
Removed the TPM hashing feature (not practical).
Fixed RSA with wolfTPM build.
Fixed cleanup wolfTPM objects on make clean.
TPM based root of trust for public key. A hash of the public key is stored in NV with auth and lock in platform.
