of/device: Set bus DMA mask as appropriate
we now get a default 32-bit bus DMA mask, and the device itself has
64-bit mask, so it gets rejected.
With the current mainline, the driver is again working (probably
because of b4ebe6063204 ("dma-direct: implement complete bus_dma_mask
handling")). But I think this is just because I happen to have < 4 GB RAM,
and it probably could still fail on bigger systems..?
