[PATCH 1/1] nvme: replace chan->device->dev with dmaengine_get_provider_device()

From: Frank Li <Frank.Li at nxp.com>

Use the dmaengine_get_provider_device() API instead of directly
accessing chan->device->dev to get the DMA provider device.

No functional change intended. Prepare make to struct dma_device private
to the DMA engine.
