Valentin Longchamp ac486e3ba1 kw_spi: support spi_claim/release_bus functions ... These two function nows ensure that the MPP is configured correctly for the SPI controller before any SPI access, and restore the initial configuration when the access is over. Since the used pins for the SPI controller can differ (2 possibilities for each signal), the used pins are configured with CONFIG_SYS_KW_SPI_MPP.
