[PATCH 7/8] ARM: dts: r8a7743: Add reset control properties

[Geert Uytterhoeven]

Add properties to describe the reset topology for on-SoC devices:
  - Add the "#reset-cells" property to the CPG/MSSR device node,
  - Add resets and reset-names properties to the various device nodes.

This allows to reset SoC devices using the Reset Controller API.

Note that all resets added match the corresponding module clocks.
