The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
But these boards don't have a memory node defined, so removing the
skeleton.dtsi inclusion in exynos4.dtsi will cause a change in the
compiled DTB. Add a dummy memory node so the compiled DTB doesn't
change if the skeleton.dtsi is removed from exynos4.dtsi.
Eventually the correct starting addresses and sizes should be used
but I didn't find that information.
