Aidan MacDonald afadb04f1d mmc: jz4740: Apply DMA engine limits to maximum segment size 
Do what is done in other DMA-enabled MMC host drivers (cf. host/mmci.c) and
limit the maximum segment size based on the DMA engine's capabilities. This
is needed to avoid warnings like the following with CONFIG_DMA_API_DEBUG=y.
