Actually there's is one reason for doing this, as it would allow devices to be monitored for device PM QoS constraints by the genpd governor. Although, I doubt's someone actually does it because of this benefit, at least yet.

Exynos4412 clock controller contains some additional clocks for FIMC-ISP (Camera ISP) subsystem. Registers for those clocks are partially located in the SOC area, which belongs to ISP power domain. This patch extends clock controller node with ISP clock sub-node and link (phandle) to ISP power domain.
