Input: tca6416-keypad - rely on I2C core to set up suspend/resume
tca6416_keypad_suspend() and tca6416_keypad_resume() only configure device
IRQ for wakeup. I2C core already does this by registering interrupt as a
wakeup IRQ in case when device is marked as wakeup-enabled, so we can
simply remove this code from the driver.
