The ASUS N-Key keyboard uses the productId of 0x1866 and is used in
almost all modern ASUS gaming laptops with slight changes to the
firmware. This patch enables: Fn+key hotkeys, keyboard backlight
brightness control.

Additionally this keyboard requires the LED interface to be
initialized before such things as keyboard backlight control work.

Signed-off-by: Luke D Jones <luke@ljones.dev>

---
Changes v8-v10
- Remove asus_wmi_send_event and change Fn+F5 to emit
  KEY_PROG4. The ASUS G14-G15 laptops have a problem
  with freezes if the user spams this key to trigger
  asus_wmi_send_event(). It is better handled with a
  key-bind and daemon.
- Change cases of dev_warn to hid_warn.
- Remove out-of-scope changes which are better suited
  as separate patches.

This version looks good to me, and it applies without problems
(no more removed spaces):
