Previously commit 166a490f59 ("wifi: ath11k: support hibernation") was
reverted due to [1], so currently we only support WoWLAN mode suspend.
This works well in scenarios where WLAN power is sustained during suspend,
however breaks in those where power is cut off.
This change basically brings the reverted commit back, but differs in that
we decide based on the PM policy to choose WoWLAN mode suspend or the
non-WoWLAN mode. As stated in the previous patch for now the PM policy is
determined based on machine models. That said we will choose WoWLAN mode
suspend if we are running on machines listed in ath11k_pm_quirk_table,
otherwise we choose the other one.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
