This patch cleans up Cygnus DT files and makes the format consistent
with the rest of Broadcom iProc based SoCs.

Changes include:
    - Put core components into "core" node of type "simple-bus"
    - Put all other peripherals into "soc" node of type "simple-bus"
    - Move aliases into bcm-cygnus.dtsi to avoid duplications in all dts
      files
    - Ordered all device nodes under buses based on their base register
      addresses
    - Remove unused PCI I/O resource
    - Use label instead of full path to reference device nodes in dts
      files
