Your patch "xen/dts: Add hypercalls to retrieve device node information"
always relies on full node patch to read device node information.

But in some cases, like GIC we don't have full patch. Here we need
to fetch node information like compatibility and other properties like number of
re-distributor regions, re-distributor offset etc., from node name.

So new set of hypercalls which take node name instead of path is required.

Vijay
