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.
