I suspect you are missing a group in pinctrl

try to add sleep group as below, and add the group to pinctrl-names so that it would be pinctrl-names = "default", "sleep";

  spi3_sleep: spi3_sleep {
        group1 {
            psels = <NRF_PSEL(SPIM_SCK, 0, 27)>,
                    <NRF_PSEL(SPIM_MOSI, 0, 10)>,
                    <NRF_PSEL(SPIM_MISO, 0, 2)>;
        };
    };

and delete the spi4 group that is not in use.

This is for using 1 SPI peripheral
