qoriq-mc's dpmacs DMA configuration is inherited from their parent node,
which acts a bus in this regard. So far it maked all devices as
dma-coherent but no dma-ranges recommendation is made.
The truth is that the underlying interconnect has DMA constraints, so
add an empty dma-ranges in qoriq-mc's node in order for DT's DMA
configuration code to get the DMA constraints from it.

Hi Shawn,
these two patches are no longer needed. This series has been superseded by this
patch[1] 951d48855d ('of: Make of_dma_get_range() work on bus nodes', available
in linux-next) which fixed the issue directly in OF code.
Sorry for the noise.
Okay, thanks for letting me know. Dropped them.
Shawn
