dt-bindings: gpu: img,powervr-rogue: Rework the allOf section

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.
