dt-bindings: power: meson-ee-pwrc: add support for Meson8/8b/8m2
The power domains on the 32-bit Meson8/Meson8b/Meson8m2 SoCs are very similar to what G12A still uses. The (known) differences are: - Meson8 doesn't use any reset lines at all - Meson8b and Meson8m2 use the same reset lines, which are different from what the 64-bit SoCs use - there is no "vapb" clock on the older SoCs - amlogic,ao-sysctrl cannot point to the whole AO sysctrl region but only the power management related registers Add a new compatible string and adjust clock and reset line expectations for each SoC.
