This property seems rather specific to the case at hand, I would expect that
one might also see routers like this that are connected to more than one
dma-device, so maybe make it a list?
It might also be better to name this as 'dma-controllers' or 'dma-masters',
as it is not entirely obvious (without referencing the binding document)
whether a dma device refers to the slave or the master.
