[v3,1/2] dt-bindings: gpio: Add STMPE YAML DT schema

  This adds a schema for the STMPE GPIO that while it is used a
lot in the kernel tree is anyway missing its bindings.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
---
ChangeLog v2->v3:
- Use a compact hog node schema backed by the standard hog
  schema.
ChangeLog v1->v2:
- New patch split off from the MFD patch.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Looks like these are not mine...

Yep, these are coming from other issues, now happening in Linus' master.
I fixed the PCI and I will send it together with the fix for media to Linus.

This should be a conversion of
Documentation/devicetree/bindings/gpio/gpio-stmpe.txt:
1. Expressed in subject, commit msg,
2. With changes against original binding mentioned in commit msg,
3. With removal of old file.
