Populate the SYSC PM domains from DT.

Special cases, like PM domains containing CPU cores or SCUs, are
handled by scanning the DT topology.

The SYSCIER register value is derived from the PM domains found in DT,
which will allow to get rid of the hardcoded values in pm-rcar-gen2.c.
However, this means we have to scan for PM domains even if CONFIG_PM=n.

FIXME:
  - This needs better integration with the PM code in pm-rcar-gen2, the
    SMP code in smp-r8a7790, and Magnus' DT APMU series.

Have you given this some thoughts already ? Unfortunately smp_prepare_cpus()
is called before any initcall :-/ How do the other platforms handle this ?

I'm afraid no other platform already handles this.

Gr{oetje,eeting}s,
