Rework the current allOf: section such that all handling of clocks/clock-names properties happens first, and all handling of power-domains/power-domain-names happens second. This allows the allOf section to limit various GPU models to matching clocks count in the first half, and apply the same for power-domains count in the second half, without conflating the two limits together. This makes addition of GPU models with different clocks and power-domains count easier. No functional change intended.
