[bugfix] x1000: Wait for FIFO to be empty rather than flushing

When data is not in packed-16-bit mode, flushing the fifo
may result in swapping left and right channels if there
happens to be an odd number of entries in the FIFO.
This is especially likely when switching sample frequencies
for some reason.

When stopping PCM DMA, disable DMA and Underrun Interrupts
and then wait for FIFO to be empty before stopping AIC's playback.
