From: Saulo Alessandre <saulo.alessandre@tse.jus.br>

* crypto/asymmetric_keys/x509_cert_parser.c
  - prepare x509 parser to load nist_secpp384r1

* crypto/ecc_curve_defs.h
  - add nist_p384 params

* include/crypto/ecdh.h
  - add ECC_CURVE_NIST_P384

* include/linux/oid_registry.h
  - reorder OID_id_ecdsa_with_sha1
  - add OID_id_secp384r1
