dt-bindings: gpio: Add DW GPIO debounce clock property
Port A of the DW GPIO controller may optionally have a debounce
logic enabled if it was synthesized with that functionality enabled.
In this case a dedicated reference clock should be declared in the
node with corresponding "db" name presented in the clock-names
property.
