[PATCH] ARM: shmobile: rcar-gen2: Drop legacy DT clock support

[Geert Uytterhoeven]

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.

To be queued in renesas-devel-for-v5.5.

The abovementioned commit was part of the v4.15 release.
The conversion was backported to v4.14.75-ltsi, and included in any
R-Car BSP based on v4.14 (rcar-3.6.0 and later).
