Remove the num-lanes property to avoid the driver setting the
link width.

On FSL Layerscape SoCs, the number of lanes assigned to PCIe
controller is not fixed, it is determined by the selected SerDes
protocol in the RCW (Reset Configuration Word).

The PCIe link training is completed automatically through the selected
SerDes protocol - the link width set-up is updated by hardware after
power on reset, so the num-lanes property is not needed for Layerscape
PCIe.

The current num-lanes property was added erroneously, which actually
indicates the maximum lanes the PCIe controller can support up to,
instead of the lanes assigned to the PCIe controller. The link width set
by SerDes protocol will be overridden by the num-lanes property, hence
the subsequent re-training will fail when the assigned lanes do not
match the value in the num-lanes property.

Remove the property to fix the issue

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.

set to "psci".

commit a13f18f5 ("Documentation: arm: Fix typo in the idle-states

needed.

Fix the cpu-capacity.txt documentation that uses the incorrect value so
we don't get copy-paste errors like these. Clarify the language in
idle-states.txt by removing the reference to the psci bindings that
might be causing this confusion.

Finally, fix devicetrees of various boards to reflect current

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.
