dt-bindings: gpio: gpio-davinci: Add the gpio-reserved-ranges property

Current definition of the davinci gpio controller doesn't include the
gpio-reserved-ranges property. Add the gpio-reserved-ranges property
so it can be used within device tree files.

Will prevent users from trying to access gpios that don't exist.
