388adff3cc pcm: Further cleanup of unused bits of the PCM ACPI:
* pcm_get_bytes_remaining()
 * pcm_calculate_peaks()
 * pcm_get_peak_buffer()

Nothing in-tree uses these at all (except for the lua plugin wrapper)

fe2d52cc7d pcm: Get rid of pcm_play_pause() and associated APIs
Nothing in the core has used it for some time.  It's exported to the
plugin API but the last plugins to use it were switched to the mixer API
back in 2011.

This allows us to get rid of pcm_play_dma_pause() from all audio drivers

286a4c5caa Revise the PCM callback system after adding multichannel audio.
Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording  uses "void **addr".
"const" is put in place throughout where appropriate.

Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

0a8235d052 Use commit_dcache() instead of commit_discard_idcache() where possible
- PCM playback DMA doesn't need the discard. Only recording DMA would
  need it.
- When creating threads for another core, the core creating the thread only
  needs to commit. The discard on the other core is handled elsewhere.
