ARM: dts: am335x: add common file for UC-2100 series 



The UC-2100 series consists many boards with different peripheral
devices and wireless modules, hence we fetch common items and
create a common dtsi file to increase reusability. All boards in
UC-2100 series will include this common dtsi file.
