Aman Kumar e922bbf375 dmaengine: idma64: Update bytes_transferred field 
Currently when 8250 data transfer is done, bytes_tranferred always returns
0 at /sys/devices/pci0000\:\:**.*/dma/dma*chan*/bytes_transferred.
In many cases it gives false impression that data is not being
trasferred via DMA.

So, updating the bytes_transferred field to count the bytes
whenever there is data transfer using idma64.
