[dpdk-dev] [PATCH 2/2] mk: disable armv8 crypto extension for Mellanox BlueField

Mellanox BlueField has a variant which doesn't have armv8 crypto extension.
If crypto enabled binary runs on such a pltform, rte_eal_init() fails. To
have binary compatibility across multiple variants, it is disabled by
default and can be enabled for crypto enabled parts.
