arm64: dts: qcom: qcs404: fix default pinctrl settings for blsp1_spi1

The current settings refer to "blsp_spi1" function which isn't defined.
For this reason an attempt to enable blsp1_spi1 interface results in
the probe failure below:

[    3.492900] qcs404-pinctrl 1000000.pinctrl: invalid function blsp_spi1 in map table
[    3.502460] qcs404-pinctrl 1000000.pinctrl: invalid function blsp_spi1 in map table
[    3.517725] qcs404-pinctrl 1000000.pinctrl: invalid function blsp_spi1 in map table
[    3.532998] qcs404-pinctrl 1000000.pinctrl: invalid function blsp_spi1 in map table
[    3.548277] spi_qup: probe of 78b6000.spi failed with error -22

Fix this by making the functions used in qcs404.dtsi to match the contents
of drivers/pinctrl/qcom/pinctrl-qcs404.c.
