    [CRYPTO] camellia: Code cleanup
    
    Move code blocks around so that related pieces are closer together:
    e.g. CAMELLIA_ROUNDSM macro does not need to be separated
    from the rest of the code by huge array of constants.
    
    Remove unused macros (COPY4WORD, SWAP4WORD, XOR4WORD[2])
    
    Drop SUBL(), SUBR() macros which only obscure things.
    Same for CAMELLIA_SP1110() macro and KEY_TABLE_TYPE typedef.
    
    Remove useless comments:
    /* encryption */ -- well it's obvious enough already!
    void camellia_encrypt128(...)
    
    Combine swap with copying at the beginning/end of encrypt/decrypt.
