dmaengine: mmp-pdma: add number of requestors
The DMA chip has a fixed number of requestor lines used for flow control. This number is platform dependent. The pxa_dma dma driver will use this value to activate or not the flow control. There won't be any impact on mmp_pdma driver. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
