Set the mclk frequency on I2S lower half by 1) checking supported
sample rate, data width and mclk multiplier table and 2) setting
this value using the I2S_MCLKFREQUENCY macro. I2S driver may or
may not implement the i2s_mclkfrequency method for setting the
master clock.
functionality. In function "wm8904_hw_reset" the priv->balance
is initialized with b16HALF, indicating a range from
0 to b16ONE. In function "wm8904_setvolume" the assumed
range for priv->balance is between 0 and 1000. The changes
now make this consistent for 0 to b16ONE-1. Furthermore,
in wm8904_configure the change of balance was not implemented.
Removes duplicate definitions in header cxd56_src.h and
includeis the proper library header samplerate.h instead.
Also corrects some related build issues.

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
