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. I tested this on an ACPI system that has a HID touchscreen and verified the IRQ was armed for wake on suspend.

It does this by looking for the wakeup-source property and setting the I2C_CLIENT_WAKE flag. This CL adds the ACPI equivalent. It uses the ACPI interrupt wake flag to determine if the interrupt can be used to wake the system. Previously the i2c drivers had to make assumptions and blindly enable the wake IRQ. This can cause spurious wake events. e.g., If there is a device with an Active Low interrupt and the device gets powered off while suspending, the interrupt line will go low since it's no longer powered and wakes the system. For this reason we should respect the board designers wishes and honor the wake bit defined on the interrupt.
