Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.
Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.
Update cooling maps to include all devices affected by individual trip
points.

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.
Add such missing properties.
Do minor rearrangement as well to keep ordering consistent.

According to PSCI standard v0.2, for CPU_SUSPEND call, which is
used by cpu idle framework, bit[16] of state parameter must be 0.
So update bit[16] of property 'arm,psci-suspend-param', which is
used as state parameter, to 0.

Move cpu_thermal node from soc node to root node.
cpu_thermal node does not have any register properties and thus
shouldn't be placed on the bus.
