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.

6a67707b5e Commit to certain names for cache coherency APIs and discard the aliases. 
Wouldn't surprise me a bit to get some non-green.

4db3e89652 Shuffle some functions around so that interfacing with playback.c in particular isn't required. Though playback does finish the audio init, pcm doesn't care who does it.

a2b6703a36 Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well.

50c547c640 M:Robe 500 and TSC2100: Add more to the initialization. Some GPIO initializations are now removed - this will be hanled by the OF or bootloader (when loading from flash).

d56999890f Make PCM->driver interface about as simple as it will get. Registered callback, zero data, alignment and stops are handled entirely inside pcm.c; driver merely calls fixed pcm.c callback. Remove pcm_record_more and do it just like playback; the original reason behind it isn't very practical in general. Everything checks out on supported targets. There wer some compat changes I can't check out on many unsupoorted but if there's a problem it will be a minor oops. Plugins become incompatible due to recording tweak-- full update. Sorted API.

3c7ada5941 Sound working with rockbox PCM interface on the M:Robe 500. Doom and Rockboy run with sound. There are stability problems that need to be looked into causing the player to reset when music playback is attempted.

e69d567d9e Bring consistency to pcm implementation and samplerate handling. Less low-level duplication. A small test_sampr fix so it works on coldfire again.
