If we do not provide the PVR for POWER8NVL, a guest on this
system currently ends up in PowerISA 2.06 compatibility mode on
KVM, since QEMU does not provide a generic PowerISA 2.07 mode yet.
So some new instructions from POWER8 (like "mtvsrd") get disabled
for the guest, resulting in crashes when using code compiled
explicitly for POWER8 (e.g. with the "-mcpu=power8" option of GCC).
