[Skiboot] [RFC PATCH V2 1/4] hdata/vpd: Reorganize VPD code

[Ananth N Mavinakayanahalli]

To make it convenient to add OpenPOWER platform support. No change in
functionality.

This series is just a preliminary RFC -- untested on real hardware. Some
of the OP HDAT/VPD updates aren't part of the firmware yet, based on the
latest HDAT blob from a Witherspoon.
