gpiolib-acpi: Don't set GPIOs for wakeup in S3 mode

commit 1796f80 ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
adjusted the policy to enable wakeup by default if the ACPI tables
indicated that a device was wake capable.

It was reported however that this broke suspend on at least two System76
systems in S3 mode and two Lenovo Gen2a systems, but only with S3.
When the machines are set to s2idle, wakeup behaves properly.

Configuring the GPIOs for wakeup with S3 doesn't work properly, so only
set it when the system supports low power idle.

Fixes: b38f2d5 ("i2c: acpi: Use ACPI wake capability bit to set wake_irq")
