    Update Gladman AES code
    
    Update lib/crypto/builtin/aes to commit
    8798ad829374cd5ff312f55ba3ccccfcf586fa11 of
    https://github.com/BrianGladman/aes .
    
    The following changes are made to the upstream code:
    
    * In aes.h, #defines are added to give the linker-visible symbols a
      prefix.
    
    * In aes.h, AES_192 is undefined, since we only need AES-128 and
      AES-256.
    
    * In aesopt.h, USE_INTEL_AES_IF_PRESENT and USE_VIA_ACE_IF_PRESENT are
      suppressed by changing the corresponding "#if 1"s to "#if 0"s.
    
    * In aesopt.h, the conditionals for ENC_UNROLL, DEC_UNROLL, ENC_ROUND,
      LAST_ENC_ROUND, DEC_ROUND, LAST_DEC_ROUND, and KEY_SCHED are changed
      from "#if 1" to "#if !defined(CONFIG_SMALL) ||
      defined(CONFIG_SMALL_NO_CRYPTO)".
