P-256K1 support in the TCG standards

[jarkkojs]

Not exactly wolfTPM issue/bug per se, but more like querying on topic.

I recently have implemented a patch set for asymmetric TPM2 RSA/ECDSA keys [1], and that made me consciously realize that P256K1 is not part of TCG Algorithm Registry. Any ideas why it has never proceeded to the registry?

Would be useful to have some day TPM_ECC_SECP_P256_K1 in the registry. Not the most secure but is used in tons of applications.
