crypto: hisilicon - Update some names on SEC V2 

1.Adjust dma map function to be reused by AEAD algorithms;
2.Update some names of internal functions and variables to
  support AEAD algorithms;
3.Rename 'sec_skcipher_exit' as 'sec_skcipher_uninit';
4.Rename 'sec_get/put_queue_id' as 'sec_alloc/free_queue_id';
