ACPICA: Allow acpi_any_gpe_status_set() to skip one GPE
The check carried out by acpi_any_gpe_status_set() is not precise enough
for the suspend-to-idle implementation in Linux and in some cases it is
necessary make it skip one GPE (specifically, the EC GPE) from the check
to prevent a race condition leading to a premature system resume from
occurring.
For this reason, redefine acpi_any_gpe_status_set() to take the number
of a GPE to skip as an argument.
