Right, that's bad.. the dt heuristics are such that each region
is mapped by a single device that it belongs to, with some rare
exceptions..

Instead, the moderately dirty way would be to expose gpucc as
syscon & pass it to the GPU device, or the clean way would be
to implement an API within the clock framework that would dump
the relevant registers
