ARM: dts: stm32: Split SoC-independent parts of DHCOM SOM and PDK2 



The DH Electronics PDK2 can be populated with SoM with any STM32MP15xx
variant. Split the SoC-independent parts of the SoM and PDK2 into the
stm32mp15xx-dhcom-*.dtsi and reduce stm32mp157c-dhcom-*dts* to example
of adding STM32MP157C variant of the SoM into a PDK2 carrier board.
