clk: shmobile: Add new Renesas CPG/MSSR DT bindings On Renesas ARM SoCs (SH/R-Mobile, R-Car, RZ), the CPG (Clock Pulse Generator) and MSSR (Module Standby and Software Reset) blocks are intimately connected, and share the same register block. Hence it makes sense to describe these two blocks using a single device node in DT, instead of using a hierarchical structure with multiple nodes, using a mix of generic and SoC-specific bindings. These new DT bindings are intended to replace the existing DT bindings for CPG core clocks ("renesas,*-cpg-clocks", "renesas,cpg-div6-clock") and module clocks ("renesas,*-mstp-clocks"), at least for new SoCs. This will make it easier to add module reset support later, which is currently not implemented, and difficult to achieve using the existing bindings due to the intertwined register layout.
