You should override the pinctrl here as you are using gpios for the cs.
				pinctrl-0 = <&pinctrl_spi0_custom>;

		pinctrl at fffff400 {
				spi0 {
					 pinctrl_spi0_custom: spi0-custom {
							 atmel,pins =
									 <AT91_PIOA 23 AT91_PERIPH_GPIO AT91_PINCTRL_NONE>,
									 <AT91_PIOA 22 AT91_PERIPH_GPIO AT91_PINCTRL_NONE>,
									 <AT91_PIOC 29 AT91_PERIPH_GPIO AT91_PINCTRL_NONE>,
									 <AT91_PIOA 14 AT91_PERIPH_GPIO AT91_PINCTRL_NONE>;
					 };
