irqchip/gic: Document optional Clock and Power Domain properties Depending on the GIC variant, the GIC module has one or more clock inputs. Document the optional "clocks" and "clock-names" properties, and their possible values, based on the Technical Reference Manuals. optional. Add the optional "power-domains" property. This will allow to describe in DT the relationship between the GIC and the Clock and/or Power Domain topology on SoCs where this is relevant and needed for proper operation. Note: As the current GIC driver doesn't support Runtime PM yet, PM Domain constraints must be handled elsewhere in e.g. platform code.
