Bug description:
  [Impact]
  Micmute hotkey on many HP ProBooks don't work.

  [Fix]
  Commit a7161e0288d1 ("hwdb: Add ProBook to use micmute hotkey"), to map AT keyboard's scancode to micmute hotkey.

  [Test]
  With the one-liner fix, micmute hotkey works on all the ProBooks I tested.

  [Where problems could occur]
  The hwdb originally only matches a few ProBooks, the fix changes that to match all ProBook models. So if there's any ProBook that uses the scancode for another purpose, there will be a regression.
  However, the risk is rather slim because HP explicitly states that all ProBooks use the same scancode for mic mute hotkey.
