As protocol driver, IFX SPI driver initiate to setup SPI master with default SPI word size as 16 bit/word, however, SPI master may not adopt this default value due to SPI controller's capability, it might choose an available value by itself and set it to spi_device.bits_per_word. In order to keep align with Controller, IFX driver should make use of this value during SPI transfer, but the default one.
