Since this warning might be elevated to an error in the future, set
coherent_dma_mask to zero because both the core and cells do not utilize
DMA.

IIUC this warning is introduced by the OF conversion and should
therefore be moved before it as a preparatory patch.

But you need to describe the problem in more detail here as this looks
fishy.
