Convert the binding file i2c-cros-ec-tunnel.txt to yaml format.
This was tested and verified on ARM and ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/google,cros-ec-i2c-tunnel.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/google,cros-ec-i2c-tunnel.yaml

Changes since v1:
- changing the subject to start with "dt-bindings: i2c: cros-ec-tunnel:"
- changing the license to (GPL-2.0-only OR BSD-2-Clause)
- removing "Guenter Roeck <groeck@chromium.org>" from the maintainers list
- adding ref: /schemas/i2c/i2c-controller.yaml
Changes since v2:
- adding another patch that fixes a warning found by this patch
Changes since v3:
- In the example, change sbs-battery@b to battery@b
Changes since v4:
- change the name of the yaml file to google,cros-ec-i2c-tunnel.yaml
- make the example more complete by adding spi0 as parent and other properties.

Change the node names so that they match the class
of the device and have a unit address.
The changes are:
bq24735 -> charger@9
smart-battery -> battery@b
This also fixes the warning:
'bq24735', 'smart-battery' do not match any of the
regexes: '^.*@[0-9a-f]+$', 'pinctrl-[0-9]+'

From my side:
Reviewed-by: Enric Balletbo i Serra <enric.balletbo@collabora.com>
We still need Rob's review and as this is a driver in the I2C
subsystem I assume this should go through the Wolfram's tree (note
that was not cc'ied, it is now). I can also pick the patch through
platform-chrome tree if Wolfram is fine.
Thanks,
Enric
