[PATCH v2 1/4] dt-bindings: input: adc-keys: allow linux,input-type property

adc-keys, unlike gpio-keys, does not allow linux,input-type as a valid
property. This makes it impossible to model devices that have ADC inputs
that should generate switch events.

Add the property to the binding with the same default as gpio-keys.
