Some registers for the Exynos 4412 ISP (Camera subsystem) clocks are
located in the ISP power domain. Because those registers are also
located in a different memory region than the main clock controller,
support for them can be provided by a separate clock controller.
This in turn allows to almost seamlessly make it aware of the power
domain using recently introduced runtime PM support for clocks.
