spi: davinci: fix SPI_NO_CS functionality
The driver should not touch CS lines if SPI_NO_CS flag is set. This patch fixes it as this functionality was broken accidentally by commit a88e34ea213e1b ("spi: davinci: add support to configure gpio cs through dt"). Fixes: a88e34ea213e1b ("spi: davinci: add support to configure gpio cs through dt") Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
