Atmel crypto engine fixes

From: Ryan Wanner <[email protected]>

I made changes to the crypto engines to fix the errors in the crypto manager tests. Mainly having to do with in-place tests with two scatter lists. These are built and tested in 6.2.7 kernel, the devices that are used for testing is the sam9x60, sama7g5, and sama5d27_som1_ek.

Adding support for zero-length messages for hmac-sha operations. Using the atmel_sha_fill_padding() function to padd the empty message manualy then disabling auto padding. This is built and tested on kernel 6.2.7 using sam9x60, sama7g5, and sama5d27_som1_ek.

Ryan Wanner (4):
crypto: atmel-sha: Add zero length message digest support for hmac
crypto: atmel-tdes - Detecting in-place operations with two sg lists
crypto: atmel-aes - Detecting in-place operations two sg lists
crypto: atmel-aes - Match cfb block size with generic implementation
