board/rde1edge: fix incorrect topology tree description

RD-E1-Edge platform consists of two clusters with eight CPUs each and
two processing elements (PE) per CPU. Commit a9fbf13e

 (plat/arm/sgi:
move topology information to board folder) defined the RD-E1-Edge
topology tree to have two clusters with eight CPUs each but PE per CPU
entries were not added. This patch fixes the topology tree accordingly.
