sparc: prom: use property "name" directly to construct node names
In preparation to remove direct accesses to the device_node.name pointer, retrieve the node name from the "name" property instead. This is slightly less optimal as we have to walk the kernel's DT property list to find the "name" property. Cc: "David S.
