the check for this can be enabled in yamllint.

dt-bindings: gpio: Add GPIO3 for AXP209 GPIO binding schema

The AXP209 has a 4th GPIO, so add it in preparation for support in the
driver.

dt-bindings: Add missing (unevaluated|additional)Properties on child node schemas

Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present.

Add unevaluatedProperties or additionalProperties as appropriate, and
then add any missing properties flagged by the addition.

dt-bindings: Remove 'Device Tree Bindings' from end of title:

As indicated in
link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/

DT schema files should not have 'Device Tree Binding' as part of there
title: line. Remove this in most .yaml files, so hopefully preventing
developers copying it into new .yaml files, and being asked to remove
it.

dt-bindings: gpio: Add AXP221/AXP223/AXP809 compatibles

These PMICs each have 2 GPIOs with the same register layout as AXP813,
but without an ADC function.

dt-bindings: gpio: Convert X-Powers AXP209 GPIO binding to a schema

The X-Powers AXP PMICs feature a GPIO Controller supported by Linux
thanks to its device tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.
