arm64: dts: lx2160a-clearfog-itx: move shared includes to dts

Originally includes were defined hierarchically:
- CEX-7 Module includes SoC
- Clearfog-CX & Honeycomb common parts include CEX-7 Module
- Boards include common parts

This makes it difficult to modify the includes on a per-board level,
e.g. when adding a new board based on CEX-7 module but revision 2 SoC
(which now has its own soc dtsi).

Move includes of both SoC and CEX-7 module out of common parts and into
each board dts.
