This adds a meson8m2.dtsi which simply inherits meson8.dtsi as both SoCs share most peripherals. The known differences are: - Meson8m2's hardware video decoder additionally supports H.265 decoding - Meson8m2 has the same Gigabit MAC as Meson8b (instead of the 10/100M MAC that Meson8 uses) - Meson8m2 uses the same watchdog register layout/bits as Meson8b (using the Meson8 watchdog compatible leads to an infinite hang when rebooting the machine) - Meson8m2 uses the same SAR ADC register layout/bits as Meson8b. However, it uses the temperature sensor calibration formula (and registers) Meson8b which differ from Meson8. This however is currently not supported by the meson-saradc driver yet. - the pin controller is mostly compatible with Meson8, Meson8m2 has an additional function on eight pins and removes the "VGA" function. So there's a total of 10 pins which are slightly changed, which is why there's a separate compatible for the pin controller - a separate compatible for the clock controller is used because at least the Mali clock tree (not supported yet) is the same as on GXBB while Meson8 and Meson8b have a reduced/older version of the Mali clock tree.
