[PATCH v5 0/3] Add support for hashing algorithms in TI DTHE V2

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

DTHEv2 is a new cryptography engine introduced in TI AM62L SoC. The
features of DTHEv2 were detailed in [1]. Additional hardware details
available in SoC TRM [2]. DTHEv2 includes, among its various
sub-components, a hashing engine which is compliant with various IETF
and NIST standards, including FIPS 180-3 and FIPS PUB 198.

This patch series adds support for the hashing algorithms
SHA224/256/384/512 and MD5 as well as their HMAC counnterparts for the
hashing engine of Texas Instruments DTHE V2 crypto driver.

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

Changelog:
v5:
 - Removed CRYPTO_AHASH_ALG_FINAL_NON_ZERO and FINUP_MAX. Implemented
   the same mechanism in the driver itself by witholding one block in
   the req ctx. 
v4:
 - Export initial state when phash_available = 0
v3:
 - Check for error in registration individualy for hash and aes driver
   algos.
 - Fixed comment style in dthev2-common.c
v2:
 - Completely revamped the driver to use the new CRYPTO_AHASH_BLOCK_ONLY
   framework for handling partial blocks and crypto_engine for queueing.
 - Added HMAC as well.
