Subject: [PATCH] wifi: mac80211: use wiphy_hrtimer_work for csa.switch_work
The work item may be scheduled relatively far in the future. As the
event happens at a specific point in time, the normal timer accuracy is
not sufficient in that case.
Switch to use wiphy_hrtimer_work so that the accuracy is sufficient. To
make this work, use the same clock to store the timestamp.

From: Benjamin Berg <benjamin.berg@intel.com>
The normal timer mechanism assume that timeout further in the future
need a lower accuracy. As an example, the granularity for a timer
scheduled 4096 ms in the future on a 1000 Hz system is already 512 ms.
This granularity is perfectly sufficient for e.g. timeouts, but there
are other types of events that will happen at a future point in time and
require a higher accuracy.
Add a new wiphy_hrtimer_work type that uses an hrtimer internally. The
API is almost identical to the existing wiphy_delayed_work and it can be
used as a drop-in replacement after minor adjustments. The work will be
scheduled relative to the current time with a slack of 1 millisecond.
