This commit is taking care of following stuff:
1. pinmux: STM32F4 micro is using I2S5_CK and I2S_SD to interface with
on-board microphone.
2. default configuration:
- enable I2S5 and configure PLLI2S properly to generate
I2SxCLK = 128MHz.
- enable DMA
Note:
As stated in issue #9028 we needed to take care of a known SPI/I2S bug
implementing the following two actions:
A. APB2 clock has been slowed down to 42MHz.
B. The SPI/I2S clock gpio speed has been set to very_high_speed.
