dmaengine: dw-edma: Drop chancnt initialization
The DMA engine core manages dma_device.chancnt itself, e.g., in
dma_async_device_register(). DMA device drivers should not initialize
chancnt because it causes the wrong number of channels printed in the
device summary.
Drop the dw-edma chancnt initialization.
