If the McBSP is doing anything at all it should still be properly
represented with the actual device rather than a dummy otherwise we'll
most likely get confused at some point. If it's not doing anything then
we shouldn't even need the dummy. But perhaps I'm confused about this
particular system, I remember some of the OMAP designs were a bit fun.

It'd be a bit of an unusual clock design for a phone but yeah.
