[PATCH v3 1/4] dt-bindings: input: add debounce-delay-ms common property

[Hugo Villeneuve <hugo@hugovil.com>]

From: Hugo Villeneuve <hvilleneuve@dimonoff.com>

A few bindings are already defining a debounce-delay-ms property, so
add it to the input binding to reduce redundant redefines.

Signed-off-by: Hugo Villeneuve <hvilleneuve@dimonoff.com>
