dmaengine: pl330: flush before wait, and add dev burst support. Do DMAFLUSHP _before_ the first DMAWFP to ensure controller and peripheral are in agreement about dma request state before first transfer. Add support for burst transfers to/from peripherals. In the new scheme, the controller does as many burst transfers as it can then transfers the remaining dregs with either single transfers for peripherals, or with a reduced size burst for memory-to-memory transfers.
