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 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.

Note that interrupts are optional, but required when the device has been
configured in keypad mode.
