pcm core: fixed spurious XRUN issues
This fixes the numerous XRUN issues seen on some cards. The trick is to set the buffer_size & period size in hw parameters. These ones are calculated from an expected maximum latency. Also, the writei is done in a loop to be robust to overruns and partial writes. Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
