dmaengine: dw-edma: Fix missing src/dst address of interleaved xfers
Interleaved DMA transfer support was added by 85e7518f42c8 ("dmaengine:
dw-edma: Add device_prep_interleave_dma() support"), but depending on the
selected channel, either source or destination address are left
uninitialized which was obviously wrong.
Initialize the destination address of the eDMA burst descriptors for
DEV_TO_MEM interleaved operations and the source address for MEM_TO_DEV
operations.
