ARM: dts: ipq4019: Remove skeleton.dtsi

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"

The disassembled DTB are almost the same besides an empty chosen node being removed and nodes reordered, so it should not have functional changes.
