crypto: keembay - CRYPTO_DEV_KEEMBAY_OCS_AES_SM4 should depend on ARCH_KEEMBAY

The Intel Keem Bay Offload and Crypto Subsystem (OCS) is only present on
Intel Keem Bay SoCs.  Hence add a dependency on ARCH_KEEMBAY, to prevent
asking the user about this driver when configuring a kernel without
Intel Keem Bay platform support.

While at it, fix a misspelling of "cipher".
