[v6,0/3] target/arm: Implement an IMPDEF pauth algorithm

Message

The architected pauth algorithm is quite slow without
hardware support, and boot times for kernels that enable
use of the feature have been significantly impacted.

Version 6 changes:
  * Rearrange xxhash64 (pmm).
  * Add documentation (pmm).
