[PATCH 3/6] ARM: meson: add support for the Meson8m2 SoCs

[Martin Blumenstingl]

Add a new Kconfig entry as well as the newly introduced compatible
string for the Meson8m2 SoC.
The Kconfig entry selects the same drivers as Meson8b because Meson8m2
SoC is mostly compatible with Meson8 (both share the same pinctrl
driver, so they also share the same GPIO IRQ settings. also the same
Meson6 timer is used on Meson8m2).
