clk: renesas: Remove R-Car Gen2 legacy DT clock support
As of commit 362b334b17943d84 ("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.
