Add a new property `function-row-physmap` to the device tree for the custom keyboard top row design.
The property describes the rows/columns of the top row keys from left to right.
Signed-off-by: Philip Chen <philipchen@chromium.org> ---
Changes in v6: - remove $ref and add `function-row-physmap` to the example
Changes in v5: - add minItems and maxItems for `function-row-physmap`
Changes in v2: - add `function-row-physmap` instead of `google,custom-keyb-top-row`
