Huge pages are not normally available to PV guests. Not suppressing
hugetlbfs use results in an endless loop of page faults when user mode
code tries to access a hugetlbfs mapped area (since the hypervisor
denies such PTEs to be created, but error indications can't be
propagated out of xen_set_pte_

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";
