Add Neoverse N1/N2/V1 as a supported cpu model.
Sorry for misleading you earlier. Looking at it now it seems that all the Neoverse CPUs are from Arm and Ampere computing only makes the Altra which is based on Neoverse N1. I guess I am not the right one to review this code, sorry for that. But I would guess we need to recognise Neoverse models as Arm and I have no idea how the Ampere behaves wrt PVR. Are you basing this on some HW as well? Thanks, Martin
