padlock.4: Update slightly for 64-bit hardware

- Change the document description to "Via and Zhaoxin CPU crypto driver"
- Add a HARDWARE section mentioning these in the hardware release note

This manual still needs desperate help, but just this little bit could
have saved a lot of confusion. I'd write more if I had information.
