ACPICA: Events: Back port "ACPICA: Save current masks of enabled GPEs after enable register writes"

This is a back port result of the Linux commit:
  Commit c50f13c672df758b59e026c15b9118f3ed46edc4
  Subject: ACPICA: Save current masks of enabled GPEs after enable register writes

Besides of the indent divergences, only a missing prototype added due to
the ACPICA internal coding style.
