c06c6ffa81 cxd56: add initial audio SRC implementation
Add basic sample rate conversion to the CXD56 Spresense audio
driver using libsamplerate. Currently conversion is only done
during playback and all output is fixed at 48 kHz.

Issues:
- 16 kHz SRC has glitches (unless data dump is enabled)
- 44.1 kHz SRC gets stuck

57e8f0451a cxd56: add initial Nuttx audio driver
Adds an initial Nuttx audio driver supporting the Spresense CXD56.
Being a work in progress the driver has a number of limitations:
- Audio playback only, no recording yet.
- Only 16 bit stereo playback is supported.
- In practice only 48kHz playback is supported due to missing SRC.
- Configure driver in "Device Drivers --> Audio Device Support".
