    Input: tca6416-keypad - always expect proper IRQ number in i2c client
    
    [ Upstream commit 687fe7dfb736b03ab820d172ea5dbfc1ec447135 ]
    
    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.
