Revert "ACPICA: Clear status of GPEs before enabling them"

Revert commit 7d90011797f3 ("ACPICA: Clear status of GPEs before
enabling them") that causes problems with Thunderbolt controllers
to occur if a dock device is connected at init time (the xhci_hcd
and thunderbolt modules crash which prevents peripherals connected
through them from working).

Commit 7d90011797f3 effectively causes commit eeea4f48b0fc ("ACPICA:
Dispatch active GPEs at init time") to get undone, so the problem
addressed by commit eeea4f48b0fc appears again as a result of it.

Fixes: 7d90011797f3 ("ACPICA: Clear status of GPEs before enabling them")
