Widening of the supported rate range in the STM32 DFSDM driver.
The rates were previously limited to 8kHz, 16kHz and 32kHz.
Allow rate capture in the whole range 8kHz-48kHz as there is no hardware
limitation to support it.
Actual sample resolution is dependent on audio rate and DFSDM configuration.
Add a trace to allow simple check of sample resolution.
