[PATCH v2 0/4] Add support for more AES modes in TI DTHEv2

[T Pratham <t-pratham@ti.com>]

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].

Change log:
v2:
 - Corrected assignment of variable unpadded_cryptlen in dthe_aead_run.
 - Removed some if conditions which are always false, and documented the
   cases in comments.
 - Moved polling of TAG ready register to a separate function and
   returning -ETIMEDOUT on poll timeout.
 - Corrected comments to adhere to kernel coding guidelines.
