[PATCH v2 11/11] ARM: shmobile: r8a7740: Add A3SM pm domain support

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

Add support for the A3SM power domain, and hook it up as a subdomain of
A4S.

This domain contains the System CPU (Cortex-A9) hardware block. Hence
move the special CPU handling from A4S to A3SM.

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

---
v2:
  - Move special CPU domain handling from A4S to A3SM,
  - Drop FIXME about not powering down A4S, as this is expected behavior.
