powerpc/pseries: Add POWER8NVL support to ibm,client-architecture-support call
commit 7cc851039d643a2ee7df4d18177150f2c3a484f5 upstream.
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).
Fixes: ddee09c099c3 ("powerpc: Add PVR for POWER8NVL processor")
