[dell-wmi] Dell Vostro 3360 extra multimedia keys don't work

[Oleksandr Natalenko <oleksandr@natalenko.name>]

Hello.

Got Dell Vostro 3360 with extra multimedia keys as shown here [1], but no luck 
to get them work.

While pressing keys "1" and/or "2" I get the following notice in dmesg:

===
dell_wmi: Unknown key e0f0 pressed
===

On pressing key "3" I get the following:

===
atkbd serio0: Unknown key pressed (translated set 2, code 0x60 on 
isa0060/serio0).
atkbd serio0: Use 'setkeycodes 60 <keycode>' to make it known.
===

Watching /proc/interrupts shows that this line:

===
9:      29836        223         96         48   IO-APIC-fasteoi   acpi
===

increments by 2 on pressing each key, and this line:

===
  1:     431013      24838       2688       2270   IO-APIC-edge      i8042
===

Also increments by 1 on pressing key "3".

Running evtest produces the following output [2] with to reaction on keys 
pressing.

acpidump output is also here [3].

Could this be fixed?
