[PATCH 11/11] [WIP] 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, and thus
must be controlled by the always-on governor.

FIXME: A3SM is never powered down during s2ram, even when adding a
       .suspend method like A4S has.
       As A3SM is a subdomain of A4S, A4S is no longer powered down
       during s2ram.
