ACPICA: Remove wakeup GPE reference counting which is not used

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.
