x86: remove special GPE handling nova <-> acpica

Remove handling of ACPI (SCI) interrupt from kernel and thereby let the
handling of the ACPI irq exclusively to an Genode driver. On Genode the ACPICA
library+app handles the ACPI irq, where we can now remove the contrib patches
related to the synchronization between NOVA kernel and ACPICA library.

Fixes #4479
