dt-bindings: iio: adc: amlogic,meson-saradc: also allow meson8-saradc to have amlogic,hhi-sysctrl property

The SARADC on the Amlogic Meson8 SoC also requires the amlogic,hhi-sysctrl,
property, document it by adding the amlogic,meson8-saradc compatible in the
adequate allOf:if:compatible:contains:enums along meson8b and meson8m2.
