crypto: arm64/aes-xctr - Add accelerated implementation of XCTR
Add hardware accelerated version of XCTR for ARM64 CPUs with ARMv8
Crypto Extension support. This XCTR implementation is based on the CTR
implementation in aes-modes.S.
More information on XCTR can be found in
the HCTR2 paper: "Length-preserving encryption with HCTR2":
