Geert Uytterhoeven Jan. 14, 2015, 12:11 p.m. UTC 
Add a device node for the System Controller, with subnodes that
represent the hardware power area hierarchy.
Hook up all devices to their respective PM domains.

Note that unlike on R-Mobile A1 (r8a7740), PM domain D4 can be powered
down without ill effects on s2ram behavior, just like on SH-Mobile AP4
(sh7372).  Hence we can postpone adding a (minimal) device node for the
Coresight-ETM hardware block.

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

v2:
  - Drop RFC state,
  - Extract addition of memory-controller nodes into a separate series,
  - Add missing 0x prefix to sysc device node register lengths.
