MXC: Correct SPI_CPOL setting in SPI driver
The handling of the SPI_CPOL bit inside the SPI driver was wrong. As reported by the manual, the meaning of the SSPOL inside the configuration register is the same as reported by SPI specification (0 if low in idle, 1 is high on idle). The driver inverts this logic. Because this patch sets the logic as specified, it is required to clear the CPOL bit in the configuration file to adapt to the correct logic.
