cpufeatures: Always advertise POWER8NVL as DD2
Despite the major version of PVR being 1 (0x004c0100) for POWER8NVL,
these chips are functionally equalent to P8/P8E DD2 levels.
This advertises POWER8NVL as DD2. As the result, skiboot adds
ibm,powerpc-cpu-features/processor-control-facility for such CPUs and
the linux kernel can use hypervisor doorbell messages to wake secondary
threads; otherwise "KVM: CPU %d seems to be stuck" would appear because
of missing LPCR_PECEDH.
Fixes: 7f4c8e8ce0b "dt: add /cpus/ibm, powerpc-cpu-features device tree bindings"
