Summary:
- This commit introduces a driver-specific spinlock to cxd56.c
to improve performance in SMP mode.
Impact:
- cxd56.c in SMP mode only
Testing:
- Tested with nxplayer and nxrecorder with the following configs
- spresense:wifi, spresense:wifi_smp

Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
g_irq_spin for backword compatibility (In this case, NULL must be specified)
Impact:
- None
Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

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

When audio fails it is usefull to have I2S transfer errors in place
to be able to track the issue

- Add new functions of GNSS
- Support the lower PWM frequency
- Add CONFIG_CPUFREQ_RELEASE_LOCK
- Add high speed ADC support
- Add HPADC input gain configuration
- Add eMMC device
- Frame buffer support
- Fix SD/GNSS/sensor drivers not worked
- Build errors
- Fix nxstyle issues
In the previous implementation, cxd56_stop() checked the internal
state before sending AUDIO_MSG_STOP to the message queue. However,
if the worker thread took time to turn on AMP, cxd560_stop() was
not able to send the message and caused a deadlock.
This commit fixes this issue by always sending AUDIO_MSG_STOP
regardless of the internal state.

Add recording support to the Nuttx audio driver for Spresense.
- Supports 16 bit data with 48 kHz sample rate only for now.
- Supports 1 (dual mono) 2 or 4 channels.
- Only analog mics have been tested so digital is considered
unsupported.
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".
