Input: iqs7222 - avoid enabling unused interrupts

If a proximity event node is defined so as to specify the wake-up
properties of the touch surface, the proximity event interrupt is
enabled unconditionally. This may result in unwanted interrupts.

Solve this problem by enabling the interrupt only if the event is
mapped to a key or switch code.
