[PATCH v4 08/16] ARM: shmobile: r8a7779 dtsi: Add CPG/MSTP Clock Domain

[Geert Uytterhoeven <geert+renesas@glider.be>]

Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.

v4:
  - Add Reviewed-by,

v3:
  - Use "CPG/MSTP Clock Domain" instead of "CPG Clock Domain",

v2:
  - New.
