ppc/pegasos2: Fix naming of device tree nodes

The board firmware names devices by their class so match that for
common devices. Also make sure the /rtas node has a name. This is
needed because VOF otherwise does not include it in results got by
nextprop which is how AmigaOS queries it and fails if no name property
is found.
