crypto: keembay-ocs-ecc - Add Keem Bay OCS ECC Driver

Browse Source 
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)
Elliptic Curve Cryptography (ECC) hardware acceleration for use with
Crypto API.
Provides OCS acceleration for ECDH-256 and ECDH-384.
Say Y or M if you are compiling for the Intel Keem Bay SoC. The
module will be called keembay-ocs-ecc.
If unsure, say N.
