[PATCH v3 11/11] ARM: shmobile: r8a7740: Add A3SM pm domain support

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 at glider.be>

v3:
- No changes,
v2:
- Move special CPU domain handling from A4S to A3SM,
- Drop FIXME about not powering down A4S, as this is expected behavior.
