crypto: caam - make aamalg_desc a proper module
The drivers/crypto/caam/ directory is entered during build only for building modules when CONFIG_CRYPTO_DEV_FSL_CAAM=m, but CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_DESC is defined as a 'bool' symbol, meaning that caamalg_desc.c is always compiled into built-in code, or not at all, leading to a link failure: ERROR: "cnstr_shdsc_xts_ablkcipher_decap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_xts_ablkcipher_encap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_aead_givencap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_aead_decap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_aead_encap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_aead_null_decap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_aead_null_encap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_rfc4106_decap" [drivers/crypto/caam/caamalg.ko] undefined! ERROR: "cnstr_shdsc_rfc4106_encap" [drivers/crypto/caam/caamalg.ko] undefined! ... Making caamalg_desc itself a loadable module fixes this configuration by ensuring the driver gets built. Aside from making the symbol 'tristate', I'm adding appropriate module metadata here.
