Usually it's not consumer's business to override resources passed from
provider, in particularly DMA coherent mask.

Can we make this conditional like in of_dma_configure():
if (!dev->coherent_dma_mask)
dev->coherent_dma_mask = DMA_BIT_MASK(32);
If not, I guess the mask has to be set before adding the spi device in
fbtft_device.c to keep it from breaking.
