Xen needs to blacklist any PSCI node as it will be recreated for DOM0.
Up to now, this was done only for arm,psci and arm,psci-0.2 compatible
nodes. Add PSCI 1.0 compatibility to make device tree nodes with
compatible = "arm,psci-1.0";
blacklisted, too

I think this is a bug fix for Xen 4.7. The impact is very limited and
will help to boot Xen on platform when only PSCI 1.0 is supported.
The patch should also be backported to Xen 4.6 where the support of PSCI
1.0 has been added for the first time.

Hmmm, I messed up my tig command line. The support of PSCI v1.0 is only
in Xen 4.7. So there is no need to backport this patch.
