[PATCH 0/2] ASoC: stm32: i2s: add power management

Add support of system low power modes to STM32 I2S driver:
Implement sleep PM suspend and resume callbacks,
to restore STM32 I2S registers after low power modes.

Add STM32 I2S peripheral and kernel clocks power management:
- Enable/disable kernel clock on audio stream startup/shutdown.
- Manage peripheral clock power through regmap services .
