Subject: [PATCH v2 0/2] Add support for Texas Instruments DTHE V2 crypto accelerator

This series adds support for TI DTHE V2 crypto accelerator. DTHE V2 is a
new crypto accelerator which contains multiple crypto IPs [1].
This series implements support for ECB and CBC modes of AES for the AES
Engine of DTHE, using skcipher APIs of the kernel.

Tested with:
CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y

and tcrypt,
sudo modprobe tcrypt mode=500 sec=1

Chnage log:
v2:
 - Corrected dt-bindings syntax errors and other review comments in v1.
 - Completely changed driver code structure, splitting code into
   multiple files
