[BUG] marvell/cesa - Fix sparse warnings breaks driver

Hi Herbert,

your patch crypto: marvell/cesa - Fix sparse warnings unfortunately
breaks the cesa driver.

I am using it on my Armada 388 board and with that patch
applied the self test stalls indefinitely.

I tried to find out which part of the patch but it seems
all of the different changes have beaking side effects.

Removing the swab is a breaking change as well as
introducing the dst_dma and src_dma variables.

Also on my 5.10 Kernel the hash tests are failing now
but this also happens when I remove your patch:

[    6.859791] alg: ahash: mv-hmac-md5 test failed (wrong result) on test vector 0, cfg="init+update+final aligned buffer"
[    6.883144] alg: ahash: mv-hmac-sha1 test failed (wrong result) on test vector 0, cfg="init+update+final aligned buffer"
[    6.923069] alg: ahash: mv-hmac-sha256 test failed (wrong result) on test vector 0, cfg="init+update+final aligned buffer"

You might need to revert the patch.

Let me know if I can debug it in any way.

Best
Sven
