[PATCH v4 11/11] soc: renesas: rcar-sysc: Add support for R-Car H3 power areas

[Geert Uytterhoeven]

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
---
v4:
  - Remove always-on power area, as it's now implicitly handled by the
    rcar-sysc driver,
  - Reformat table,

v3:
  - New (converted from DT to C).
