ufs-pltfrm: initialize DMA mask for device-tree probed device
The device-tree probed device for ARM doesn't have dev->dma_mask.
So dma_set_mask() for the device doesn't succeed. The popular trick
for this is - dev->dma_mask = &dev->coherent_dma_mask;
Currently there is no dma_set_mask() call in ufs-pltfrm, but the
forthcoming fix needs proper DMA mask setting in ufs core driver. So
initializing dev->dma_mask as described above is required.
