f1e866b106 crypto: arm - add support for GHASH using ARMv8 Crypto Extensions 
This implements the GHASH hash algorithm (as used by the GCM AEAD
chaining mode) using the AArch32 version of the 64x64 to 128 bit
polynomial multiplication instruction (vmull.p64) that is part of
the ARMv8 Crypto Extensions.
