The current code would always use the speed and mode set by CONFIG_ENV_SPI_MAX_HZ and CONFIG_ENV_SPI_MODE. But if using SPI driver model it should get the values from DT.

Why not just use spi_flash_probe() with speed and mode passed as 0?

As Simon said spi_flash_probe() "is an old-style function and would be removed when all SPI flash drivers use dm", so I think for dm spi_flash_probe_bus_cs() should be used.
