Subject: [PATCH] docs: power: update documentation about removed function

The function cm_notify_event() was removed in commit 9584051f3cf3
("power: supply: charger-manager: Remove cm_notify_event function").
Remove the documentation that suggests how it can be used.

Signed-off-by: Julia Lawall <Julia.Lawall@...ia.fr>

---

There is also a reference to cm_notify_event in
drivers/power/supply/charger-manager.c that is less clear what to do
with:

        /*
         * Charger-manager is capable of waking up the system from sleep
         * when event is happened through cm_notify_event()
         */
	device_init_wakeup(&pdev->dev, true);
        device_set_wakeup_capable(&pdev->dev, false);

-5. Notify Charger-Manager of charger events: cm_notify_event()
-==============================================================
-If there is an charger event is required to notify
-Charger Manager, a charger device driver that triggers the event can call
-cm_notify_event(psy, type, msg) to notify the corresponding Charger Manager.
-In the function, psy is the charger driver's power_supply pointer, which is
-associated with Charger-Manager. The parameter "type"
-is the same as irq's type (enum cm_event_types). The event message "msg" is
-optional and is effective only if the event type is "UNDESCRIBED" or "OTHERS".
