ARM: dts: r8a7792: Add reset control properties 



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 resets usually match the corresponding module clocks.
Exceptions are:
  - The audio module has resets for the Serial Sound Interfaces only,
    but audio is not yet enabled in r8a7792.dtsi,
  - The display module has only a single reset for all DU channels, but
    adding reset properties for the display is postponed.
