1. Bump top level address-cells/size-cells nodes to 2 (to ensure all
down stream addresses are 64-bits, unless explicitly specified
otherwise (in "soc" bus with all peripherals)
2. "memory" also specified with address/size 2
3. Add a commented reference for PAE40 region beyond 4GB physical
address space
