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.
