Merge "Renesas ARM Based SoC DT PM Domain Updates for v4.7" into next/late

* Add SYSC PM Domains to DT for R-Car Gen 1 and 2 SoCs

This pull requests is based on a merge of:

* "[GIT PULL] Second Round of Renesas ARM Based SoC R-Car SYSC Updates for
  v4.7", tagged as renesas-rcar-sysc2-for-v4.7, which you have already
  pulled.
* "[GIT PULL v2] Renesas ARM Based SoC DT Updates for v4.7",
  tagged as renesas-dt-for-v4.7, which you have also already pulled.

The reason for the somewhat tedious base on
renesas-rcar-sysc2-for-v4.7, which provides driver changes,
is a hard run-time dependency.

I also have a similar set of changes for arm64 which I will send separately.
