DTHEv2 is a new cryptography engine introduced in TI AM62L SoC. The
features of DTHEv2 and details of AES modes supported were detailed in
[1]. Additional hardware details available in SoC TRM [2].

This patch series adds support for the following AES modes:
 - AES-XTS
 - AES-CTR
 - AES-GCM
 - AES-CCM

The driver is tested using full kernel crypto selftests
(CRYPTO_SELFTESTS) which all pass successfully [3].
