As it turns out, even a 4-way interleave is not sufficient to saturate the ThunderX2 pipeline with AES instructions, so this series implements 5-way interleave for modes that can be modified without running out of registers to maintain chaining mode state across the encryption operation, i.e., ECB, CBC-decryption and CTR.
