Merge #490

490: I2s rework r=burrbull a=YruamaLairba

Hi, I'm currently rewriting stm32_i2s crates, and i try to reflect my change and implement an example here in parallel for validation. 

I'm currently stuck on a requirement i have. Using I2s in slave mode require to read a pin in alternate mode and in a generic way. I don't know how to implement that, so i will open an issue for that.
