ARM: configs: at91: sama7: Enable crypto IPs and software algs

Similar to sama5_defconfig, enable hardware acceleration for the
sama7 crypto IPs, enable crypto software implementations in case
the crypto IPs need a fallback to them, and enable the hash and
skcipher user interfaces in case one wants to offload the crypto
algs to the sama7 crypto IPs.
