ACPI: PM: Take wake IRQ into consideration when entering suspend-to-idle
This change adds support for ACPI devices that use ExclusiveAndWake or SharedAndWake in their _CRS GpioInt definition (instead of using _PRW), and also provide power resources. 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. Signed-off-by: Raul E Rangel <rrangel@chromium.org> Signed-off-by: Rafael J.
