ARM: davinci: devices-da8xx: Add dma_slave_map to edma
Provide the dma_slave_map to edma which will allow us to move the drivers to the new, simpler dmaengine API and we can remove the DMA resources also for the devices. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> [nsekhar@ti.com: fix map for edma1] Signed-off-by: Sekhar Nori <nsekhar@ti.com>
