To support Rx in-band wakeup, one must create an interrupt specifier with
edge sensitivity on Rx pin and an addtional pinctrl to reconfigure Rx pin
to normal GPIO in sleep state. Driver will switch to sleep mode pinctrl and
enable irq wake before suspend and restore to default settings when
resuming.

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-Arm cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Arm CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

The '#address-cells' and '#size-cells' properties were not defined in
the lm3630a bindings and would cause the following error when
attempting to validate the examples against the schema:

'#address-cells', '#size-cells' do not match any of the regexes:
'^led@[01]$', 'pinctrl-[0-9]+'

Correct this by adding those two properties.

While we're here, move the ti,linear-mapping-mode property to the
led@[01] child nodes to correct the following validation error:

Documentation/devicetree/bindings/leds/backlight/lm3630a-backlight.example.dt.yaml:
