Shijith Thotton 2d841af23a crypto: octeontx2 - remove CONFIG_DM_CRYPT check 
No issues were found while using the driver with dm-crypt enabled. So
CONFIG_DM_CRYPT check in the driver can be removed.

This also fixes the NULL pointer dereference in driver release if
CONFIG_DM_CRYPT is enabled.

...
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008

Ovidiu Panait 06f6e365e2 crypto: octeontx2 - set assoclen in aead_do_fallback() 
Currently, in case of aead fallback, no associated data info is set in the
fallback request. To fix this, call aead_request_set_ad() to pass the assoclen.

Srujana Challa 6f03f0e8b6 crypto: octeontx2 - register with linux crypto framework 
CPT offload module utilises the linux crypto framework to offload
crypto processing. This patch registers supported algorithms by
calling registration functions provided by the kernel crypto API.

The module currently supports:
- AES block cipher in CBC,ECB and XTS mode.
- 3DES block cipher in CBC and ECB mode.
- AEAD algorithms.
  authenc(hmac(sha1),cbc(aes)),
  authenc(hmac(sha256),cbc(aes)),
  authenc(hmac(sha384),cbc(aes)),
  authenc(hmac(sha512),cbc(aes)),
  authenc(hmac(sha1),ecb(cipher_null)),
  authenc(hmac(sha256),ecb(cipher_null)),
  authenc(hmac(sha384),ecb(cipher_null)),
  authenc(hmac(sha512),ecb(cipher_null)),
  rfc4106(gcm(aes)).
