Would be useful here to explain why client drivers need to change
idle modes.

Also, this patch is telling me that it's time the McBSP is converted
over to the omap_hwmod/omap_device infrastructure where this type
of functionality would already be provided.

Not necesssarily a reason to prevent this patch for now, but this
will all need to be changed when converted to hwmod.
