crypto: inside-secure - Add support for the ecb(sm4) skcipher

Browse Source 
This patch adds support for SM4 in ECB mode, i.e. skcipher ecb(sm4).

changes since v1:
- make SAFEXCEL_SM4 case entry explit, using the proper SM4_BLOCK_SIZE
  instead of "borrowing" the AES code which "coincidentally" works
