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

Mediatek's Keypad controller is used to interface a SoC with a matrix-type
|
|
keypad device. The keypad controller supports multiple row and column lines.
|
|
A key can be placed at each intersection of a unique row and a unique column.
|
|
The keypad controller can sense a key-press and key-release and report the
|
|
event using a interrupt to the cpu.
