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.

e0bb92f00f Should clear up rest of red. Add a required #define in the config for c200. Fix up some preprocessing directives. Hope it's all taken care of now.

c3eca575b6 Fix red. Thought I had REC_SAMPR_DEFAULT covered if not otherwise specified as different than 44.

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.

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

bcb8a884ee e200: Add recording. Just from MIC right now and FM integration will happen soon. Most every bit of weirdness is nescessary and no problems seem to exist that the retailos doesn't exhibit too (namely noise when LCD is on when recording from MIC).

fd8dd686f4 Default HW_SAMPR_CAPS should be SAMPR_CAP_44, not 0.
