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.

Previously the ACPI subsystem had no idea if the device had a wake capable interrupt armed. This resulted in the ACPI device PM system placing the device into D3Cold, and thus cutting power to the device. With this change we will now query the _S0W method to figure out the appropriate wake capable D-state.
