ASoC: stm32: sai: add stm32mp25 support
Add STM32MP25 support for STM32 SAI.
On STM32MP25 the SAI driver does not manage SAI kernel clock rate
by chosing its parent clock, dependending on audio stream rate.
The driver requests a rate change on SAI kernel clock instead.
This rate change is performed with the following guidelines:
- Chose highest rate multiple of the audio stream
(Try to get clock accuracy within 1000 ppm)
- Ensure clock rate compatibility between SAI sub-blocks A&B
and between instances sharing the same flexgen.
Use clk_rate_exclusive API to fulfill this requirement.
The STM32 SAI peripheral does not support the DMA burst mode
on STM32MP25. Add a field in compatible structure to manage DMA
burst support capability.
