Add the 'uncached-offset' property to be used for specifying the
uncached memory offset required for handling non-coherent DMA
transactions.

Only one offset can be non-coherent? If this is for DMA, why
dma-noncoherent cannot be used?

As Conor already mentioned in [1], the handling of non-coherent DMA on 
RISC-V is currently being worked on, so I expect this patch will be dropped.
