dmaengine: add dmaengine_get_provider_device() API
Add dmaengine_get_provider_device() API and kernel doc for
dmaengine_get_dma_device() to describe the difference.
dmaengine_get_dma_device() is used for DMA mapping because some DMA
engines provide per-channel iommu mapping.
dmaengine_get_provider_device() is used to find a DMA engine channel
by a filter function.
In most cases they return the same value, but they have different
semantic meanings.
