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.

Hmm... I am not sure about this. The entire kernel has only two drivers that
do that, and thanks to their commit messages one of them pointed out to the
commit from 2018. So, if no other devices suffer from this, I think it has to
be a better way of achieving the same.
