powerpc/512x: fix the hanged dma transfer issue
Current code clears interrupt active status _after_ submitting new
transfers. This leaves a possibility of clearing the interrupt for this
new transfer (if it is triggered fast enough) and thus lose this
interrupt. We want to clear interrupt active status _before_ new
transfers is submitted and for current channel only.
