Use the ADC channel 1 to check the hardware revision of the board and detect the N2 vs. N2+ and the C4 vs. HC4 variants. Each of them use different dtb file, so adjust fdtfile environment variable to the detected variant. The ADC min/max values for each variant are taken from the vendor code, adjusted to the 12-bit ADC driver operation mode (vendor code use 10-bit mode).
