dt-bindings: gpio: Convert STMPE GPIO to YAML schema
This rewrites the STMPE GPIO bindings to a YAML schema.
We add the properties that are used in the widely used
STMPE GPIO device nodes found in the wild, most notably
interrupt support, so interrupt-cells and
interrupt-controller is now part of the bindings.
