HeXin Tech Co. has applied for a new PVN from the OpenPower Community
for its new processor C2000. The OpenPower has assigned a new PVN
and this newly assigned PVN is 0x0066, add pvr register related
support for this PVN.

Why is this not in sorted order?
It's semantically sorted :D
ie. HX_C2000 is most similar to POWER8, but is newer than it.
Yes. This is what I mean. If you prefer to sort in another order, please 
tell me and I will update this.
PVR_BE is out of place, I'll fix that.

cheers
