Bug description:
[Impact]
Mic mute key is no function on HP Elite Dragonfly.
[Fix]
After confirming with HP, there are two model names for Dragonfly:
* HP Elite Dragonfly G2 Notebook PC
* HP Elite Dragonfly Max Notebook PC
Thus, the commit
Commit c1b8c966eccb7be1cae0a30670f5e1fcd88b47fa maps the 81 scan code to mic
mute key.
[Test]
After patching it, the mic mute key could functioned well on my Dragonfly
laptop.
[Where problems could occur]
There is not old rule for Dragonfly dmi string in current hwdb.
Which means the Dragonfly is using default HP key map:
```
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnHP*:pn*:*
KEYBOARD_KEY_81=fn_esc
```
This patch will change the HP machine (if product name contains
pnHPEliteDragonfly*) to map 81 to mic mute key.
If a machine (pnHPEliteDragonfly*) works good in the past then this patch may
cause it's mic mute key become malfunction.
However, this rule is confirmed/provided from HP.
