PATCH 1/1 ARM: dts: realview-pbx: Fix duplicate regulator nodes

There's a bug in dtc in checking for duplicate node names when there's another section (e.g. "/ { };"). In this case, skeleton.dtsi provides another section. Upon removal of skeleton.dtsi, the dtb fails to build due to a duplicate node 'fixedregulator@0'. As both nodes were pretty much the same 3.3V fixed regulator, it hasn't really mattered. Fix this by renaming the nodes to something unique. In the process, drop the unit-address which shouldn't be present wtihout reg property.
