[PATCH 4/4] arm: layerscape: ppa: Add PPA as /reserved-memory/ppa node

Instead of adding a /memreserve/ entry, add the PPA as a
/reserved-memory/ppa node. For the Kernel it doesn't make a difference,
but using a node makes the range visible in /sys/firmware/devicetree and
the node name also gives a hint what the region is reserved for.
