ASoC/mpc5200: get rid of the appl_ptr tracking nonsense
Sound drivers PCM DMA is supposed to free-run until told to stop
by the trigger callback. The current code tries to track appl_ptr,
to avoid stale buffer data getting played out at the end of the
data stream. Unfortunately it also results in race conditions
which can cause the audio to stall.
