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.
