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.
