e189b33ff4 Clean up peak calculating code. 
Mixer needn't keep peak data around that will never be used. Just
pass pcm_peaks structure to it instead of allocating for every
channel. Plugin API becomes incompatible.

vu_meter digital mode was still using global peak calculation;
switch it to playback channel like the rest.

Remove some accumulated soil peaks inside pcm.c and make it more
generic.

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.

e42a3194de AS3525v1/v2: 
Fix problems with volume of recorded material by converting 14-bit samples to
16-bit. Remove duplicate samples from recorded data and support proper
samplerate since ADC runs 1/2 the codec clock. Support monitoring mono on both
output channels by feeding data manually to I2SOUT under the right conditions.

DMA is no longer used for recording since frames must be processed as described
above but it does allow full-duplex audio.

Miscellaneous change includes a proper constant (HW_SAMPR_DEFAULT) to reset the
hardware samplerate when recording is closed. PP5024 and AS3525 have different
default recording rates (22kHz and 44kHz respectively) but both have half-speed
ADC.

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.

b15a523870 e200v1/c200v1: Implement limited samplerate switching. Rates 24kHz and below are being a bear as far as minor crackling at higher amplitude-- leave them out for the time being since no solution is currently evident. 48, 44, 32 (rec rates 24, 22, 16) seem perfectly fine. I'm betting c200 is ok to include because it uses the same setup as e200.

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.

4d04132c76 PCM bottom layer simplification. pcm_rec_peak_addr variable no longer has to be handled there. Driver can just return current pointer for recording peaks. A new define, HAVE_PCM_REC_DMA_ADDRESS, specifies that physical addresses are being used for recording and translation is needed before starting a new block. The drivers need not worry about aligning start and size nor should care if either will be zero. All this will be checked in the logical layer first.

- Keymaps are definitely not perfect, touchscreen targets are disabled due to no keymap
- There is no manual yet

93572e2a9e Keyclick fixup take two. It is only 88 samples (2msec) long so keep a small static buffer around for beeps less than or equal to keyclick duration. This way it operates no matter the buffer state and still won't interfere with alternate PCM operations like recording or plugin playback.

05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).
