ARM: common: edma: clear completion interrupts on stop
When stopping a DMA transfer with interrupts disabled it is possible
that the DMA transfer completes before the events are cleared. In
this case the completion interrupt will be pending, causing a
completion callback after the transfer was stopped.
By clearing the completion interrupt for the stopping channel it is
ensured that no completion event will be generated after the stop.
