Input: tca6416-keypad - always expect proper IRQ number in i2c client

Browse Source 
Remove option having i2c client contain raw gpio number instead of proper
IRQ number. There are no users of this facility in mainline and it will
allow cleaning up the driver code with regard to wakeup handling, etc.
