hid-plantronics uses a custom input mapping, where unhandled usages get
ignored. Although these headsets have telephony buttons (microphone mute
and answer/hangup), they are not handled in plantronics_input_mapping,
hence not exposed to the userspace. This commit fixes it by adding a
case for HID_UP_TELEPHONY to the "basic telephony compliant" devices.
Tested with Plantronics Blackwire 3220 Series (047f:c056).
