ARM: dts: imx7d: Add missing cooling device properties for CPUs

The cooling device properties "#cooling-cells" 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.
