That's board-specific information. I'd rather not include it in the SoC
.dtsi file even as a default; that way, it forces people to think about
the correct value and put it in their board file, whereas including a
default means people probably won't think about it.

Of course, that'll need updating based on the resolution of the clock
binding thread I started.
