This change removes the explicit enable_irq_wake / disable_irq_wake and instead relies on the PM subsystem. This is done by calling dev_pm_set_wake_irq. i2c_device_probe already calls dev_pm_set_wake_irq when using device tree, and i2c_device_remove also already calls dev_pm_clear_wake_irq. There could be some device tree systems that have incorrectly declared `wake` capabilities, so this change will set the wake irq if one is missing. This matches the previous behavior.
