8bc780106c board: amlogic: odroid: add runtime detection of the N2/N2+/C4/HC4 variants
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).

21cd92faa5 ARM: dts: meson-sm1: add U-Boot specific DT for graphics
Rename meson-g12a-u-boot.dtsi into meson-g12-common-u-boot.dtsi to
match the new DT architecture and add meson-sm1-sei610-u-boot.dtsi
to handle the U-Boot specific DT for graphics.

ce9fa7bffc ARM: dts: meson-g12a: add U-Boot specific DT for graphics
Like the meson-gx support, add the U-Boot specific bits in DT
to support graphics on G12A SoCs.
