crypto: cryptd - Adding the AEAD interface type support to cryptd
This patch adds AEAD support into the cryptd framework. Having AEAD
support in cryptd enables crypto drivers that use the AEAD
interface type (such as the patch for AEAD based RFC4106 AES-GCM
implementation using Intel New Instructions) to leverage cryptd for
asynchronous processing.
