Input: soc_button_array - add mapping for airplane mode button

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.

While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.
