Without an alias the Linux SPI bus number is assigned dynamically and can change with the carrier board or probe order. Add a spi0 alias so the bus number in sysfs and the spidev name follow the Verdin interface numbering, zero-based with SPI_1 being spi0. This replaces the spi0 alias imx8mp.dtsi gives to flexspi, Verdin QSPI_1, which gets a dynamic bus number instead.
