From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
The driver will be modified (in the next commits) to be able to specify
individual power domain ID for each IP. The driver will still
support #power-domain-cells = <0>, thus, previous users are not
affected.
The #power-domain-cells = <1> has been instantiated only for RZ/G3S at
the moment as individual platform clock drivers need to be adapted for
this to be supported on the rest of the SoCs.
Also, the description for #power-domain-cells was updated with the links
to per-SoC power domain IDs.
