Add support for the Hashing Control Unit (HCU) included in the Offload Crypto Subsystem (OCS) of the Intel Keem Bay SoC, thus enabling hardware-accelerated hashing on the Keem Bay SoC for the following algorithms: - sha256 - sha384 - sha512 - sm3 The driver is composed of two files: - 'ocs-hcu.c' which interacts with the hardware and abstracts it by providing an API following the usual paradigm used in hashing drivers / libraries (e.g., hash_init(), hash_update(), hash_final(), etc.). NOTE: this API can block and sleep, since completions are used to wait for the HW to complete the hashing. - 'keembay-ocs-hcu-core.c' which exports the functionality provided by 'ocs-hcu.c' as a ahash crypto driver. The crypto engine is used to provide asynchronous behavior. 'keembay-ocs-hcu-core.c' also takes care of the DMA mapping of the input sg list. The driver passes crypto manager self-tests, including the extra tests (CRYPTO_MANAGER_EXTRA_TESTS=y).
