In some configurations the touch controller can support the touch-keys.
Document the linux,keycodes property that enables those keys and
specifies the keycodes that should be used to report the key events.

Changes in v2:
- Include input.yaml schema at the top level instead of at the
property. (Seems like I still can't think of the schema as device
and not implementation-specific thing...)
- Reword the description to be more informative.
