wifi: ath11k: choose default PM policy for hibernation
Now WoWLAN mode is chosen for those machines listed in the quirk table.
This works for suspend (S3) but breaks for hibernation (S4), because
WoWLAN mode requires WLAN power to be sustained, which is not the case
during hibernation. For hibernation, the default mode should be used.
Register a PM notifier with which kernel can notify us of the actual PM
operation: if system is going to suspend, the original PM policy is
honored; while if it is hibernation, overwrite it with default policy.
To summarize: for suspend (S3), WoWLAN mode is chosen for machines listed
in the quirk table, non-WoWLAN mode for others; for hibernation (S4),
non-WoWLAN mode is chosen for all.
