While here, constify the source of the platform data.

We pass struct dw_dma_chip to dw_dma_probe() anyway, thus we may use it to
pass a platform data as well.

While here, constify the source of the platform data.

Instead of creating a new platform device leaf they may call dw_dma_probe() with given struct dw_dma_chip directly and make sure that the main device is DMA capable.
