My first thought with this is that it's not something I'd expect to be in the device tree at all - it looks like it's all properties of the silicon which I'd expect the drivers to be able to figure out for themselves without needing to be told by the device tree.
There is no way for the software to know what the FIFO depth is, so this is the sort of thing that should be in the device tree.
Are you saying that every DT for a system doing audio on a PowerPC system has to manually specify the depth of the FIFO on the silicon? That doesn't sound particularly sensible, and I had been under the impression that DT systems had a better way of coping with this.
