Maxime Ripard 0202a32d5f spi: spi-gpio: Add checks for the dt properties ...

The bindings assumed that the gpios properties were always there, which
made the NO_TX and NO_RX mode not usable from device tree. Add extra
checks to make sure that the driver can work if either MOSI or MISO is
not used.
