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.
