fix AcpiEnableGpe:
GPEs get enabled at ACPI initialization. AcpiInstallGpeHandler() disables
GPEs using AcpiEvDisableGpe() w/o decrementing RuntimeCount.
So when acpiec(4) enables the GPE after installing the GPE Handler then
AcpiEnableGpe() does not call AcpiEvEnableGpe() because RuntimeCount
says it is already enabled which is wrong.
So decrement the RuntimeCount in AcpiInstallGpeHandler() right
before calling AcpiEvDisableGpe().
