Wiping board SPI flash which contained old U-boot and using 2025.01 from 
SD card fixed issue hence DTS is OK.
Though I do not remember that I ever wrote anything into SPI flash in 
first place (I touched board almost year ago so potentially forgot about 
it) maybe it was shipped like that with the board...
