* smcLoadSecureExpModKey no longer exists.

* smcLoadSecureExpModKey/smcLoadRsaOaepKey/smcDecryptRsaPrivateKey no longer exist.

* smcLoadRsaOaepKey has been replaced with a new SMC (0xC300D60C) that loads two keys into TrustZone.

* smcDecryptRsaPrivateKey was replaced with smcDecryptOrImportRsaPrivateKey.

** All keys which were previously imported with specific keys now first call smcEncryptRsaPrivateKeyForImport with the appopriate enum member to get a sealed copy of the RSA key, then smcDecryptOrImportRsaPrivateKey to import/unseal the key when needed.

* smcGetConfig was extended with two new config items:
