KM Kirkwood boards now implement the driver model for its SPI flash interface. Therefore, the old board specific claim and release functions can be deleted. The preprocessor definition CONFIG_SYS_KW_SPI_MPP is yet unused as well. All its appearances and dependencies are removed in the kirkwood_spi driver, header files and finally the configuration whitelist.
