The iomuxc node in board dts is a little special now, and it will have a
lot more data than others.  I like Alexander's idea to put it at the
bottom of the file to make it easier for users to check board level
settings of other device nodes.  So I would suggest that way for the new
added iomuxc node in board dts.
