There are 2 issues related to the enabling of GPEs:
1. Currently, our code clears GPE before enabling it. In case of edge
triggered GPEs, doing this risks GPE losses.
2. For edge-triggered GPEs, enabling it is not sufficiently to trigger an
already triggered GPE, we need to poll the GPE once it is enabled.
This patchset fixes these 2 problems.

ACPICA: Events: Stop unconditionally clearing ACPI IRQs during
suspend/resume
ACPICA: Events: Dispatch GPEs after enabling for the first time
