Feel free to add my tag to the series. Let me know any more help with testing is required.

To handle the Lenovo unexpected wakeup issue [1], previously we revert commit 166a490f59ac ("wifi: ath11k: support hibernation"). However we need to bring it back, of course with additional changes such that Lenovo machines would not break. As those machines work well in Non-WoWLAN suspend mode, the thought here is that we do WoWLAN suspend on Lenovo machines while do non-WoWLAN suspend (which is done in the reverted commit) on other machines. This requires us to identify Lenovo machines from others. For that purpose, read machine info from DMI interface, match it against all known affected machines. If there is a match, choose WoWLAN suspend mode, else choose non-WoWLAN mode.
