[PATCH/RFC v2 02/11] soc: renesas: Move pm-rcar to drivers/soc/renesas/

[Geert Uytterhoeven <geert+renesas@glider.be>]

Move the pm-rcar driver to drivers/soc/renesas/, so it can be shared
between arm32 (R-Car H1 and Gen2) and arm64 (R-Car Gen3).

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v2:
  - New.
