ARM: dts: am3517-evm: Split off SOM features from baseboard
The am3517-evm consists of an am3517 SOM-M2 and a baseboard.
As items are added that are unique to the baseboard, let's place
them in a file called am3517-som.dtsi. These items will be
common for all variants of the SOM.
Anything unique to the baseboard will be placed into
am3517-evm.
