On Meson GXL, GXM, AXG, G12A, G12B & SM1 SoCs, we can generate an unique
MAC address if none valid found in the eFuses storage.
Only the GXBB based boards doesn't have a fallback way to generate an
unique MAC address, so we rely on CONFIG_NET_RANDOM_ETHADDR to have
a valid one.
An exception is the Radxa Zero board who doesn't have Ethernet on board
so depends on an (or multiple) eventual USB adapters, so leaving the
CONFIG_NET_RANDOM_ETHADDR configs seems safer.

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).
