初始化和配置函数。
===============================================================================
##### Initialization and de-initialization functions #####
===============================================================================
[..] This subsection provides a set of functions allowing to initialize and
de-initialize the I2Sx peripheral in simplex mode:
(+) User must Implement HAL_I2S_MspInit() function in which he configures
all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC ).
(+) Call the function HAL_I2S_Init() to configure the selected device with
the selected configuration:
(++) Mode
(++) Standard
(++) Data Format
(++) MCLK Output
(++) Audio frequency
(++) Polarity
(+) Call the function HAL_I2S_DeInit() to restore the default configuration
of the selected I2Sx peripheral.
