dma_alloc_coherent takes a device parameter in Linux, which allows it to
device-specific non-1:1 mapping as well as different coherent DMA mask
and coherency settings.
To enable handling these quirks in future, let's add the device
parameter and set it to DMA_DEVICE_BROKEN for now.
This should introduce no functional change.
