The pl330 dmaengine driver used to be split into two mostly separate drivers. In
commit b7d861d939 ("DMA: PL330: Merge PL330 driver into drivers/dma/") those two
parts were merged into one driver. The abstraction layers that were previously
used to communicate between the two independent parts, although now mostly
unused and unnecessary, were kept. This makes the driver more complex than it
has to be. This series tries to clean the driver up a bit by removing the unused
parts and also doing a bit of simple restructuring at the end. This is done to
make it easier to add new features (like proper residue reporting) to the
driver.
