[PATCH 1/1] drivers: define OPENSSL_API_COMPAT

[Heinrich Schuchardt]

The API of the OpenSSL library has changed with version 3.0. This results
in a lot of compiler warnings like

    ../dpdk/drivers/crypto/ccp/ccp_crypto.c:182:9:
    warning: ‘SHA256_Transform’ is deprecated:
    Since OpenSSL 3.0 [-Wdeprecated-declarations]

As many Linux distributions still use elder OpenSSL libraries we cannot
change the used API now. Instead define OPENSSL_API_COMPAT to indicate
that we are using the OpenSSL 1.1.0 API.

OPENSSL_API_COMPAT is introduced in *.c files and not in *.h files as some
*.c files directly include OpenSSL headers.
