hwdb: fix warning "atkbd serio0: Unknown key pressed" (#5772)

Browse source 
At each time pressing the WiFi Fn key on Dell Latitude E7270 laptop, the system
reports the following error/warning messages:

  atkbd serio0: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0).
  atkbd serio0: Use 'setkeycodes e008 ' to make it known.

This is due to commit 0e33634 which was added to fix
https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1441849.

However on Dell Latitude E7* models, we need to restore the old generic
behavior which consists in ignoring the key event since it's already done by
the HW.

Indeed the hardware has a specific driver (dell_wmi) to handle rfkill in the
hardware level. So, as long as the hardware handles, the best is to leave as
is.

This patch was originally written by Takashi Iwai.
