40 is invalid. It should be in the range 0-31.

Try gpio-sck = <&gpio1 8 GPIO_ACTIVE_LOW>;

Also, why are you doing spi-gpio?

Looking at the pinctrl driver, these pins can be used by a real SPI
core:

        MPP_MODE(39,
                MPP_VAR_FUNCTION(0x0, "gpio", NULL,      V(0, 0, 0, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x1, "ts", "mp3",       V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x2, "tdm", "spi-cs0",  V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x4, "audio", "bclk",   V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0xb, "lcd", "d19",      V(0, 0, 0, 0, 1, 0))),
        MPP_MODE(40,
                MPP_VAR_FUNCTION(0x0, "gpio", NULL,      V(0, 0, 0, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x1, "ts", "mp4",       V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x2, "tdm", "spi-sck",  V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x4, "audio", "sdo",    V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0xb, "lcd", "d20",      V(0, 0, 0, 0, 1, 0))),
        MPP_MODE(41,
                MPP_VAR_FUNCTION(0x0, "gpio", NULL,      V(0, 0, 0, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x1, "ts", "mp5",       V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x2, "tdm", "spi-miso", V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x4, "audio", "lrclk",  V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0xb, "lcd", "d21",      V(0, 0, 0, 0, 1, 0))),
        MPP_MODE(42,
                MPP_VAR_FUNCTION(0x0, "gpio", NULL,      V(0, 0, 0, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x1, "ts", "mp6",       V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x2, "tdm", "spi-mosi", V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0x4, "audio", "mclk",   V(0, 0, 0, 1, 1, 0)),
                MPP_VAR_FUNCTION(0xb, "lcd", "d22",      V(0, 0, 0, 0, 1, 0))),
