spi: spi-fsl-dspi: add SPI_LSB_FIRST to driver capabilities
The driver as well as the controller support the SPI lsb first mode. However, it's not possible to configure it e.g. when using spidev. Adding this flag to mode_bits resolves the issue and lsb first mode can be used. Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
