[PATCH 3/4] dt-bindings: thermal: amlogic,thermal: add power-domains

[George Stark]

On newer SoCs, the thermal hardware can require a power domain to
operate so add corresponding property as optional by default and as
required for Meson A1 due to it's temperature sensor has dedicated
power domain.
