ARM: dts: imx6qdl-dhcom: Split SoC-independent parts of DHCOM SOM and PDK2

The DH electronics PDK2 can be populated with SoM with i.MX6S/DL/D/Q
variants. Split the SoC-independent parts of the SoM and PDK2 into the
imx6qdl-dhcom-*.dtsi and reduce imx6q-dhcom-pdk2.dts to example of
adding i.MX6S/DL/D/Q variants of the SoM into a PDK2 carrier board.
