Subject: [PATCH 0/2] ASoC: stm32: dfsdm: change rate limits

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.
