With the introduction of 55c7c0621078 ("ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations") the firmware bus has to comply with /soc's DMA limitations. Ultimately linking both buses to a same dma-ranges property. The patch (and author) missed the fact that a bus' #address-cells and #size-cells properties are not inherited, but set to a fixed value which, in this case, doesn't match /soc's. This, although not breaking Linux's DMA mapping functionality, generates ugly dtc warnings. Fix the issue by adding the correct address and size cells properties under the firmware bus.
