Add a device node for the System Controller.
Hook up the first Cortex-A15 CPU core and the Cortex-A15 L2 cache/SCU to
their respective PM Domains.

v6:
- Add Acked-by,
v5:
- Remove "power-domains" property again from the sysc node, as the
System Controller itself is not part of the Clock Domain,
v4:
- Add "power-domains" property to the sysc node, to refer to the SoC's
Clock Domain,
v3:
- Drop power area hiearchy from DT,
- Switch to "#power-domain-cells = <1>",
- Drop fallback compatibility strings,
v2:
- Change one-line summary prefix to match current arm-soc practices,
- Update compatible values.
