From: Rafael J. Wysocki <rjw@xxxxxxx>
After the previous patch that introduced acpi_gpe_wakeup() and
modified the ACPI suspend and wakeup code to use it, the third
argument of acpi_{enable|disable}_gpe() and the GPE wakeup
reference counter are not necessary any more. Remove them and
modify all of the users of acpi_{enable|disable}_gpe()
accordingly. Also drop GPE type constants that aren't used
any more.
