Prabhjot Khurana c9f608c380 crypto: keembay-ocs-ecc - Add Keem Bay OCS ECC Driver
The Intel Keem Bay SoC can provide hardware acceleration of Elliptic
Curve Cryptography (ECC) by means of its Offload and Crypto Subsystem
(OCS).

Add the Keem Bay OCS ECC driver which leverages such hardware
capabilities to provide hardware-acceleration of ECDH-256 and ECDH-384.

Support for Intel Keem Bay Offload and Crypto Subsystem (OCS) AES and
SM4 cipher hardware acceleration for use with Crypto API.
Provides HW acceleration for the following transformations:
cbc(aes), ctr(aes), ccm(aes), gcm(aes), cbc(sm4), ctr(sm4), ccm(sm4)
and gcm(sm4).
Optionally, support for the following transformations can also be
enabled: ecb(aes), cts(cbc(aes)), ecb(sm4) and cts(cbc(sm4)).
