dmaengine: stm32-dma3: introduce ddata2dev helper

Browse source

The purpose of this helper is to 'standardize' device pointer retrieval,
similar to the chan2dev() helper.
ddata2dev() helper returns the device pointer from struct dma_device stored
in stm32_dma3_ddata structure.
Device pointer from struct dma_device has been initialized with &pdev->dev,
so the ddata2dev helper returns &pdev->dev.
