ACPI: don't duplicate input events on netlink
The previous events patch added a netlink event for every
user of the legacy /proc/acpi/event interface.
However, some users of /proc/acpi/event are really input events,
and they already report their events via the input layer.
Introduce a new interface, acpi_bus_generate_netlink_event(),
which is explicitly called by devices that want to repoprt
events via netlink. This allows the input-like events
to opt-out of generating netlink events. In summary:
events that are sent via netlink:
ac/battery/sbs
thermal
processor
thinkpad_acpi dock/bay
events that are sent via input layer:
button
video hotkey
thinkpad_acpi hotkey
asus_acpi/asus-laptop hotkey
sonypi/sonylaptop
