clk: renesas: Remove R-Car Gen2 legacy DT clock support

As of commit 362b334 ("ARM: dts: r8a7791: Convert to new CPG/MSSR bindings"), all upstream R-Car Gen2 device tree source files use the unified "Renesas Clock Pulse Generator / Module Standby and Software Reset" DT bindings. Hence remove backward compatibility with old R-Car Gen2 device trees describing a hierarchical representation of the various CPG and MSTP clocks.
