SPI control functions.

 ===============================================================================
                      ##### Peripheral State and Errors functions #####
 ===============================================================================
    [..]
    This subsection provides a set of functions allowing to control the SPI.
     (+) HAL_SPI_GetState() API can be helpful to check in run-time the state of the SPI peripheral
     (+) HAL_SPI_GetError() check in run-time Errors occurring during communication
