ARM: STi: DT: STih407: Abstract common dt nodes into shared files. 

The stih410 soc which will be added in the following commit is very similar to
the stih407, to enable maximum re-use of the dt files this commit abstracts the
common parts into a shared dt file stihxxx-b2120 for the board, and also a shared
file stih407-family.dtsi for the SoC.
