ACPI / EC: Use busy polling mode when GPE is not enabled commit c3a696b6e8f8f75f9f75e556a9f9f6472eae2655 upstream. When GPE is not enabled, it is not efficient to use the wait polling mode as it introduces an unexpected scheduler delay. So before the GPE handler is installed, this patch uses busy polling mode for all EC(s) and the logic can be applied to non boot EC(s) during the suspend/resume process.
