The BTMTKSDIO_BT_WAKE_ENABLED flag is set for bluetooth interrupt
during system suspend and increases wakeup count for bluetooth event.

Changes in v3:
- Replace deprecated macro.

Changes in v2:
- Add Bluetooth prefix to patch subject
- Fix warnings regarding using plain integer as NULL
- Add static to btmtksdio_pm_ops

Changes in v1:
- Add BTMTKSDIO_BT_WAKE_ENABLED flag
- Call pm_wakeup_event in btmtksdio_interrupt
