Do we truly need P-128? Besides, I do not see that

Do we truly need P-128? Besides, I do not see that curve being defined in
contemporary cipher specs.

1. Add some new 'ECDH' curve parameter definitions to
'include/crypto/ecc_curve_defs.h', and reorder ECC 'Curves IDs'
in 'include/crypto/ecdh.h';
2. Enable 'ECDH' algorithm in Kunpeng 930.
