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.

Could you please point me Alexander's patch for reference? I was not able to locate it.
