ACPICA: Introduce acpi_any_gpe_status_set()

Browse Source 
Introduce a new helper function, acpi_any_gpe_status_set(), for
checking the status bits of all enabled GPEs in one go.

It is needed to distinguish spurious SCIs from genuine ones when
deciding whether or not to wake up the system from suspend-to-idle.
