[PATCH] spi: spi-fsl-dspi: add SPI_LSB_FIRST to driver capabilities

[Kurt Kanzenbach]

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.
