[Bug 1930910] [NEW] Fix micmute hotkeys on HP ProBooks

[Kai-Heng Feng]

Public bug reported:

[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.
