ASoC: stm32: i2s: add stm32mp25 support

Add STM32MP25 support for STM32 I2S.

On STM32MP25 the I2S driver does not manage I2S kernel clock rate
by choosing its parent clock, depending on audio stream rate.

The driver requests a rate change on I2S kernel clock instead.
It tries to set the higher possible rate, which is a multiple of
the audio stream rate and which gives an accuracy of at least 1000 ppm.
