[PATCH] spi: fsl: Fix driver breakage when SPI_CS_HIGH is not set in spi->mode

[Christophe Leroy <christophe.leroy@xxxxxxxxxx>]

Commit 766c6b63aa04 ("spi: fix client driver breakages when using GPIO
descriptors") broke fsl spi driver.

As now we fully rely on gpiolib for handling the polarity of
chip selects, the driver shall not alter the GPIO value anymore
when SPI_CS_HIGH is not set in spi->mode.
