We have for the H3 boards some kind of cargo cult apparently, where we
would have a pinctrl node even for GPIOs without any particular settings.
This is pretty much useless, so let's remove them.

So far we've enabled pull-up and pull-down resistors on GPIOs using a
pinctrl node. Now that the GPIO binding allows for a flag to declare this,
let's switch to it.
This brings us closer to removing all the GPIO pinctrl nodes, which will in
turn allow us to switch the pinctrl strict mode on.

A83T DTSI has cpu clocks defined only on the first CPU in each cluster.
We can bring down any CPU in the cluster, so we need to define clock
for each CPU, so that the system knows what clock to use if the first
CPU is down.
Also move the clocks property below the compatible on cpus where it is
already defined. Property "clock-names" is not needed.

Enable to use CPUs as cooling device in the future, by adding
"#cooling-cells" to each CPU node. This property should be present for
all the CPUs of a cluster. 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.
