rfkill: add the WWAN radio type

Unfortunately, instead of adding a generic Wireless WAN type, a technology-
specific type (WiMAX) was added.  That's useless for other WWAN devices,
such as EDGE, UMTS, X-RTT and other such radios.

Add a WWAN rfkill type for generic wireless WAN devices.  No keys are added
as most devices really want to use KEY_WLAN for WWAN control (in a cycle of
none, WLAN, WWAN, WLAN+WWAN) and need no specific keycode added.
