After "spi: spi_flash_probe_bus_cs() rely on DT for spi speed and mode" series flash speed and mode wasn't passed to driver anymore, which resulted in:
Loading Environment from SPIFlash... tegra20_sflash spi@7000c380: Invalid chip select 0:0 (err=-19) *** Warning - spi_flash_probe_bus_cs() failed, using default environment
Fix it by syncing SPI node of affected device dts with Linux kernel dts. The changed SPI bus frequency doesn't influence stability of read/write operations.
