From: Tomasz Maciej Nowak <tmn505 at gmail.com>
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 at 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.
