[PATCH v5 3/3] dt-bindings: input: Update dtbinding for adp5588

From: Utsav Agarwal <utsav.agarwal@analog.com>

Updating dt bindings for adp5588. Since the device can now function in a
purely gpio mode, the following keypad specific properties are now made
optional:
- interrupts
- keypad,num-rows
- keypad,num-columns
- linux,keymap

However since the above properties are required to be specified when
configuring the device as a keypad, dependencies have been added
such that specifying either one would require the remaining as well.
