[0/3] Bluetooth: Prevent scanning when device is not configured for wakeup

Message

Hi linux-bluetooth,

This patch series adds a hook to prevent Bluetooth from scanning during
suspend if it is not configured to wake up. It's not always clear who
the wakeup owner is from looking at hdev->dev so we need the driver to
inform us whether to set up scanning.

By default, when no `prevent_wake` hook is implemented, we always
configure scanning for wake-up.

Thanks
Abhishek
