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,
- The display module has only a single reset for all DU channels, but
adding reset properties for the display is postponed.
