In a subsequent patch, the registration callback will need more parameters from cpg_mssr_priv (like another base address with clock controllers with double register block, and also, notifiers and rmw_lock). Instead of adding more parameters, move the needed parameters to a public sub-struct. Instead moving clks to this structure, which would have implied to add an allocation (and cleanup) for it, keep the way the allocation is done and just have a copy of the pointer in the public structure.
