mx6: mx6qsabrelite/nitrogen6x: Remove incorrect setting of gpio CS signal
The number of gpio signal is packed inside CONFIG_SF_DEFAULT_CS macro (shifted and or'ed with chip select), so it's incorrect to pass that macro directly as an argument to gpio_direction_output() call. Also, SPI driver sets the direction and initial value of a gpio, used as a chip select signal, before any actual activity happens on the bus. So, it is safe to just remove the gpio_direction_output call, that works incorrectly, thus making no effect, anyway.
